AUTHOR'S   PREFACE. 


It  is  now  over  nine  years  since  the  preparation  of  this 
volume  was  first  begun,  the  pressure  of  other  work  having 
continually  hindered  its  completion.  It  was  inevitabh^  that 
during  so  long  a  period  changes  should  have  taken  place  in 
one's  opinions  and  methods,  and  as  it  was  impossible  to 
re-examine  all  the  material  dealt  with  in  the  earlier  stages, 
certain  inequalities  of  treatment  have  resulted,  for  which 
indulgence  mnst  be  asked. 

It  is  with  the  greatest  pleasure  that  I  acknowledge  my 
indebtedness  to  numerous  friends  and  correspondents,  without 
whose  kindly  assistance  I  could  not  have  hoped  to  complete 
this  first  instalment  of  my  work.  Of  the  older  collections  of 
CuRCULiONiDiE  the  most  important  is  that  in  the  Stockholm 
Museum,  which  contains  the  types  of  Gyllenhal,  Boheman, 
Chevrolat,  etc.,  and  all  of  these  have  been  entrusted  to  mo 
for  examination  by  my  friend  Prof.  Dr.  Yngve  Sjostedt  j 
while  both  he  and  Prof.  Dr.  C.  Auriviilius  have  helped  me 
with  most  engaging  kindness  during  my  various  visits  to 
their  beautiful  citv.  Of  modern  collections  of  Cukculionid.E 
by  far  the  most  important  is  that  accumulated  by  the 
distinguished  specialist  on  this  family,  the  late  Johannes 
Faust,  who  described  some  2300  new  species  from  all  parts 
of  the  world.  This  collection  is  now  in  the  Dresden  Museum 
under  the  charge  of  Dr.  K.  M.  Keller,  to  whom  I  am  under  /-/  / 

a  great  obligation  for  the  loan  of  numerous  types  of  species  / 

described  by  both  Faust  and  himself.     In  the  Civic  Museum  ' 

at  Genoa  there  is  a  valuable  collection  of  Coleoptera  made  in 


VI  PilEFAfE. 

Bui'ina  by  Leonardo  Fea  containing  nearly  200  new  sj)ec'ie.s 
of  Weevils  described  by  Faust;  of  these  Dr.  K.  Gestro  has 
Leon  good  enough  to  entrust  to  me  not  merely  the  types  of 
the  species  T  required,  but  the  whole  series  of  specimens  in 
each  case.  IMr.  H.  E.  Andrewes  has  greatly  assisted  my 
work  by  ])lacing  at  my  dis])osal  a  fine  collection  of  Indian 
Weevils,  all  named  by  Faust  and  comprising  numerous 
co-types.  I  have  also  to  exjiress  my  thanks  to  the  following 
gentlemen  for  the  loans  of  various  types: — Prof.  E.  B. 
Poulton,  F\R.S.,  for  the  Schlinherrian  tyj)es  from  the  Hope 
collection,  Oxford  ;  the  late  Prof,  Dr.  Ganglbauer  of 
Vienna,  for  ty])es  of  S])ecies  described  l)y  Uedteiibacher  from 
Kashmir;  Prof.  Kolbe,  of  the  Zoological  Museum  at  Berlin, 
for  some  of  Herbst's  ty})es  ;  Dr.  Taschenberg.  of  Halle,  for 
types  from  Germar's  colh^ction ;  M.  Severin  and  Dr.  H. 
Schouteden,  of  the  Brussels  Museum,  for  types  described  bv 
Desbrochers  des  Loges  ;  the  late  M.  Desbrochers  des  Loges. 
for  tv{)es  from  his  own  collection;  and  Di".  N.  Annandalc, 
of  the  Indian  ]Museum.  for  types  of  various  sjiecies  described 
bv  Faust  and  F)esbrochers. 

This  work  has  ])een  ]irinci])ally  l)ased  on  the  tine  series 
of  Indian  sjxicics  contained  in  the  British  IMuseum,  and 
I  cannot  refrain  from  ex])ressing  mv  sincere  thanks  to 
Mr.  G.  J.  Arrow,  of  that  Institution,  for  the  courteous 
assistance  which  he  has  always  so  reatlily  afforded  me.  But 
a  very  large  stipply  of  unnamed  material  has  also  been 
received  from  various  correspondents  in  India  and  on  the 
(Continent,  among  whom  my  special  thanks  are  due  to  Prof. 
H,  Maxwell  Lefroy  ;  Mr.  T.  Bainbrigge  Fletcher,  Imperial 
Entomologist,  Pusa  ;  Mr.  F.  H.  Gravely,  Indian  Museum, 
(Jalcuita  ;  Dr.  A.  D.  Imms  ;  Mr.  (\  F.  ('.  Beeson,  Imperial 
Forest  Zoologist,  I)ehra  Dun  :  Mr.  E.  Ballard,  Government 
ICntomologist,  Madras;  Mr.  E.  E.  Green,  late  Govern- 
ment Entomologist,  Ceylon;  M.  8everin,  of  the  Brussels 
Museum  ;  M.  Albert  Bovie,  of  ]3i-us?els  :  M.  Pierre  Lesne,  of 
the  Paris  Museum;  and  particularly  to  Mr.  H.  E.  Andrewes, 


PRKFACE.  VII 

who  has  entrusted  to  nie  the  rich  collection  made  by  his 
nephew,  Mr.  H.  L.  Andrewes,  principally  in  the  Nilgiri 
Hills,  together  w^ith  nmch  interesting  material  received  from 
his  other  correspondents,  including  Mr.  T.  R.  D.  Bell, 
Gapt.  A.  K,  Weld  Downing,  Mr.  C.  Somers  Smith,  Mr.  H. 
Stevens,  and  the  late  Mr.  G.  Q.  Corhett.  Mr.  Andrewes  has 
generously  permitted  the  iypes  of  practically  all  the  new 
species  described  Fron\  his  collection  to  be  presented  to  the 
British  Museum. 

In  1871,  when  Gemminger  and  Harold  published  their 
Catalooue  of  the  Curculionid.e  of  the  World  the  total 
number  of  species  recorded  from  within  the  limits  of  this 
Fauna  was  only  324.  At  the  time  of  Faust's  death  in  1903, 
the  number  had  risen  to  approximately  IIHH).  In  this 
volume  342  species  are  dealt  with,  of  which  just  over  one- 
half  are  here  described  for  the  first  time.  On  this  basis  it 
is  estimated  that  the  number  of  Indian  species  at  present 
existing  in  collections  must  be  little  short  of  2000 ;  and 
when  the  country  has  been  |)roperly  worked  by  competent 
collectors,  it  is  more  than  likely  tSiai  that  nnmlx'r  will  be 
doubled.

INTEODUCTION. 


S  uborder    RHYNCHOPHORA . 

The  Cueculionid.i:,  or  Weevils,  belong  to  a  very  well-marked 
division  of  the  Coleoptera,  which  is  generally  treated  as  a  sub- 
order under  the  name  of  Ehynchopiiora,  But  although  the 
members  of  this  assemblage  can  be  readily  recognised  by  their 
general  facies,  no  single  structural  feature  has  yet  been  dis- 
covered which  characterises  all  the  species  to  the  exclusion  of 
other  Coleoptera. 

As  lirst  pointed  out  by  J.  X.  Leconte  ('  American  Xaturalist,' 
1874,  p.  385;  Proc.  American  Phil.  Soc.  xv,  1876,  p.  1),  the 
most  representative  characteristics  of  the  suborder  are  the  con- 
solidation of  the  sclerites  on  the  lower  surface  of  the  head 
and  on  the  prosternum ;  of  these  the  cephalic  structure  is  the 
more  important. 

In  normal  Coleoptera  tliere  will  be  observed  on  the  posterior 
portion  of  the  lower  surface  of  the  head  two  longitudinal  sutures, 
either  straight  or  curved,  and  varying  in  their  direction  and 
approximation.  These  are  known  as  the  gular  sutures,  and  the 
piece  lying  between  them  is  the  gula.  In  the  Ehynchophora, 
with  a  few  exceptions,  the  gula  has  entirely  disappeared  and 
there  is  only  a  single  median  suture,  which  itself  is  sometimes 
evanescent  or  even  absent  (fig.  2).  Leconte  stated  that  this 
coalescence  of  the  gular  sutures  did  not  occur  in  any  species 
outside  of  the  suborder,  but  this  has  been  contested  by  H.  J. 
Kolbe  (Arch.  Naturg.  1901,  Beihelt,  p.  95),  who  says  that  in 
certain  genera  of  the  Passaxdrin^  (Cucujid.i:)  and  TrogositiD-t: 
the  gular  structure  is  similar  to  that  in  the  Ehynohophora.  I 
have  been  luiable  to  confirm  the  latter  statement,  for  in  all  the 
genera  which  I  have  examined  of  the  groups  specified  two  gular 
sutures  are  undoubtedly  present. 

Per  the  present,  therefore,  we  may  accept  the  disappearance 
of  the  gula  as  a  character  peculiar  to  the  Rhynchophora.  But 
Dr.  C.  J.  Gahan  has  pointed  out  that  there  are  a  few  genera  in 
the  group  for  which  it  does  not  hold  good  ('  Entomologist,'  xliv, 
1911,  p.  217)  ;  these  are  lihinoviacer  and  Oxycorijnus  (CuRCU- 
LioNiD^),  and   some    ycOLYTin.E,    such   as    Crossotarsus.      AVith

Z  KHysrCHOPHORA. 

regard  to  the  last-named  instance,  Dr.  Gaban  informs  me  that 
he  has  since  ascertained  that  when  the  two  gular  sutures  are 
present  in  the  Platypodix.i;,  the  character  is  a  serual  one,  the 
sutures  uniting  in  the  female,  while  in  the  male  they  are  con- 
tinued independently  to  the  hind  margin  of  the  head. 

In  the  case  of  the  prosternum,  the  points  which  are  specially 
characteristic  of  the  Ehynchophora  are  the  disappearance  of  the 
two  sutnres  that  separate  the  prosternum  (the  central  piece 
before  the  front  coxae)  from  the  side-pieces  or  plein'a3,  and  the 
fusion  of  the  epimera  in  the  middle  line  behind  the  coxae.  To 
both  of  these  characters  there  are  exceptions.  The  prosteriial 
sutnres  are  present  in  the  Riiinomaoehin.e,  and  traces  of  them 
near  the  coxae  can  be  observed  in  many  genera  of  Curculionid^ 
(fig.  7).  As  regards  the  fusion  of  the  epimera,  the  only  apparent 
exceptions  in  the  suborder  known  to  me  are  the  African  Cur- 
culionid  genera  HopUtotrachelus,  .Schh.,  and  Biirsoj^s,  Schh.,  which 
comprise  the  subfamily  Bybsopin.i;.  In  these  insects,  if  examined 
externall)',  the  epimera  appear  to  be  separated  by  an  appreciable 
interval ;  but  if  the  prothorax  be  removed  and  examined  in- 
ternally, it  will  be  found  that  the  posterior  portion  is  fused  into 
a  solid  ring  without  any  trace  of  a  suture. 

In  the  other  suborders  of  Culeoptera  the  prosternal  epimera 
are  separated,  with  a  few  exceptions,  such  as  the  Megalopodid^ 
among  the  Phytophaga,  Cossyplms  and  Endostomus  (Tene- 
BRiONiD.i:),  certain  Lagriii).!;,  and  the  genus  JVemaiidium  among 
the  CucuJiD.E  ;  but  in  none  of  these  insects  are  the  pieces  fused 
together  as  in  the  Kliynohophora. 

Various  attempts  have  been  made  to  subdivide  the  Ehyn- 
chophora  into  a  number  of  families,  the  new  families  proposed 
having  been  for  the  most  part  extracted  from  the  Ccrculioxid.i:. 
But  those  authors  who  have  gone  furthest  in  splitting  up  this 
family  liave  made  no  special  study  of  these  insects  as  a  whole, 
and  when  the  attempt  is  made  to  apply  their  classifications  to 
faunas  with  which  they  were  not  well  acquainted,  the  results 
have  proved  far  from  satisfactory.  In  the  present  state  of  our 
knowledge,  therefore,  it  seems  preferable  to  follow  Lacordaire, 
David  Sharp  and  Ganglbauer  in  recognising  only  the  four  main 
families,  Anthribid,^,  Curculionid.s:,  ScoLYTin.E*  and  Bken- 
THiD.i,  together  with  the  two  small  and  highly  aberrant  groups, 
Peoterhixii»,e  and  Aglyctderid^,  which  do  not  occur  within 
our  limits. 

Owing  to  the  presence  of  various  convergent  forms,  it  is  not 
easy  to  lay  down  hard  and  fast  lines  of  demarcation  between 
several  of  these  families,  but  the  following  key  will  perhaps  assist 
in  their  discrimination.

CURCULIONID^. 


Family   CURCULIONIDiE. 

The  real  foundations  of  our  luiowledge  of  this  multitudinous 
family  of  beetles  were  first  laid  in  the  monumental  work  pro- 
duced by  the  four  eminent  Swedish  entomologists,  Schcinherr, 
Boheman,  Gyllenhal  and  Fahraeus  ('  Genera  et  Species  Curcu- 
lionidum',  vols,  i-viii,  1833-45),  in  which  603  genera  and  some 
6550  species  were  described,  only  between  600  and  700  species 
having  been  known  previously.  The  only  subsequent  attempt 
to  survey  the  CrRCULiONiDiE  of  the  world  as  a  whole  is  contained 
in  Lacordaire's  '  Genera  des  Coleoptures  '  (vols,  vi  &  vii,  1863 
&  1866).  In  this  work  he  recognised  834  genera,  which  were 
divided  into  82  "  tribes  "  or  subfamilies.  His  classification  was 
based  on  thoroughly  sound  lines  and  was  an  immense  advance 
on  Schonherr's  superficial  arrangement  of  the  family.  It  is 
true  that  many  modifications  in  his  system  have  been  rendered 
necessary  as  a  result  of  the  enormous  increase  in  the  number 
of  described  genera  and  species  during  the  last  fifty  years,  but

nevertheless  Lacordaire's  classification,  on  account  of  its  com- 
prehensive character,  remains  to-day  the  standard  one  for  the 
student  who  has  to  deal  with  the  weevils  of  any  fauna  other 
than  those  of  Europe  or  North  America. 

AS'^lieu  Gemminger  and  von  Harold  published  their  Catalogue 
of  the  Curculionidae  in  1871,  the  number  of  described  species 
known  to  them  amounted  to  10,150,  and  there  can  be  little 
doubt  that  the  number  to-day  would  run  to  well  over  20,000. 
A  thorough  revision  of  this  large  assemblage  of  geiiera,  already 
much  overdue,  is  essential  for  a  true  appreciation  of  their  inter- 
relationships, but  such  a  task  was  quite  impossible  in  connexion 
with  the  preparation  of  the  present  volume,  and  the  altei-native

adopted  has  been  to  take  Lacordaire's  arrangement  as  a  working 
basis,  making  only  such  akei'ations  as  are  necessary  for  the 
inclusion  of  the  numerous  Indian  species  which  wer9.  unknown

Structure  of  the  Imago. 

Rostrum. — The  most  striking  characteristic  of  the  CuKCU- 
LiOiS'iDyE  is  the  prolongation  of  the  head  in  front  of  the  eyes, 
forming  a  rostrum  or  bealv  (fig.  2)  which  bears  the  antennse,  the 
mouth  being  situated  at  its  extreme  apex.  This  structure  varies 
immensely  in  its  shape  and  development ;  at  one  end  of  the 
series  it  is  extremely  short,  and  almost  as  broad  and  deep  as  the 
head  in  certain  terrestrial  Australian  species  (Amycterus)  and 
in  a  few  Scolytid-like  forms  among  the  CossoNiN.ii,  while  in 
Balaninus  it  is  very  slender  and  may  be  even  longer  than  the 
whole  body  ;  and  every  intergrade  between  these  extremes  may 
be  found.  Along  each  side  of  the  rostrum  tliere  is  always  a 
well-marked  hollow  or  furrow,  the  scrobe,  in  which  the  antenna 
is  placed,  the  furrow  being  used  for  tlie  reception  of  the  elongate 
first  joint,  or  scape,  when  in  a  position  of  rest.  The  shape  and 
position  of  the  scrobe  afford  useful  taxonomic  characters  (fig.  ] ).

Mouth- parts  (figs.  2-5). — The  mouth-parts  are  contained  in  the 
terminal  aperture,  or  buccal  cavity,  and  in  the  species  with  a 
slender  rostrum  thej^  are  naturally  much  r(?duced  in  size.  The 
most  noticeable  feature  is  the  great  reduction  of  the  palpi,  which 
are  invariably  very  short  and  rigid  (except  in  the  Eiii>'OMACERTN^Ti:). 
and  often  entirely  concealed.  In  various  groups  the  mentum 
exhibits  striking  differences  in  its  relation  to  the  otlier  parts  of 
the  mouth  (fig.  3),  and  this  was  utilised  by  Lacordaire  in  his 
primary  division  of  the  family  into  Curculionid.tj  Adelogivathi 
and  CuECULioNiD^  Phaneeognaxhi.  In  the  Adelognathi 
(figs.  3,  «,  and  4,  rt,  c)  the  large,  obtuse  and  pincer-like  mandibles 
occupy  the  greater  part  of  the  buccal  cavity  and  the  small  space 
left  behind  them  is  completely  or  almost  completely  filled  by  the 
mentum.     In  the  completely  adelognathous  genera   the  maxillae

and  their  palpi  are  entirely  hidden,  and  there  is  no  supporting 
peduncle  projecting  from  the  submentum.  But  in  some  genera 
there  is  a  very  short  and  broad  peduncle,  and  in  such  cases  the 
base  of  the  maxilla  is  visible  on  each  side  ;  the  maxillar}'  palpi, 
however,  are  always  concealed  when  the  mouth  is  closed,  though 
an  insect  will  sometimes  die  with  its  palpi  exserted  beyond  the 
front  margin  of  the  mentum. 

In  the  Phanerogn'athi  the  mentum  assumes  much  more 
varied  shapes  (tig.  3^  5,  c,  d)  and  is  nearly  always  supported  on 
a  marked  process  emitted  by  the  submetitum.  In  these  insects 
the  maxillary  palpi  are  clearly  visible,  lying  on  each  side  of  the 
mentum,  and  the  mandibles  are  much  more  slender  and  pointed ; 
but  this  does  not  apply  to  the  Sii'alix.i:,  in  which  the  condition 
of  the  mouth-parts  is  quite  abnormal  (tig.  3,  <?),  tlie  peduncle 
having  apparently  become  fused "with  the  edges  of  the  emargina- 
tion  of  the  submentum  in  which  it  normally  lies,  so  that  the 
buccal  cavity  is  reduced  to  a  transverse  slit  at  the  apex  of  the 
rostrum,  only  the  mandibles  being  visible.  An  allied  Eastern 
genus,  Cnjptoderma  (0.r>jrhi/nchiis),  presents  what  appears  to  be 
a  transitional  condition  in  this  direction.

The  maxillfe  are  always  slender  in  those  species  in  which  thev 
are  hidden  by  the  mentum,  but  in  the  other  section  they  are 
often  a  good  deal  stouter,  and  especially  in  an  Australian  sub- 
family, the  AMrcTEKi>'.i;,  in  which  they  are  broad  and  fused  to 
the  sides  of  the  mentum.  They  have  normally  only  a  single 
lobe,  and  even  this  is  evanescent  in  the  species  with  a  very 
slender  rostrum.  The  place  of  the  missing  outer  lobe  is  occupied 
by  the  palpus. 

Among  the  Adelogxathi  the  mandibles  present  a  character 
the  significance  of  which  was  first  explained  by  Lacordaire  (Gen. 
Coleop.  vi,  p.  5),  and  was  subsequently  shown  by  Leconte  to  be 
of  considerable  taxonomic  importance.  If  the  mandibles  of  one 
of  the  BrackyderiNtE  or  OTiORRHYJfCHiN^^  be  examined  from 
in  front,  there  will  be  observed  on  each  a  more  or  less  rounded 
or  oval  area,  which  is  sometimes  merely  flattened,  but  is  more 
often  slightly  hollowed  (fig.  4).     The  edge  of  this  area  is  nearly

always  slightly  raised  above  the  adjoining  surface  oi:  the  mandible, 
but  in  many  Tanymecides  it  is  markedly  prominent  and  can  be 
readily  seen  when  the  end  of  the  rostruui  is  viewed  from  above 
(fig.  4,  b).  This  structure,  which  is  known  as  the  mandibular 
scar,  serves  as  a  support  for  a  temporary  false  mandible  (fig.  5), 
or  mandibular  appendage,  which  in  the  vast  majority  of  species 
normally  breaks  off  soon  after  the  emergence  of  the  adult,  though 
persisting  in  a  few  exceptional  individuals  ;  there  are,  however, 
a  few  genera  in  which  it  appears  to  be  retained  permanently, 
namely,  in  both  sexes  of  the  Pahiearctic  Psalidium,  and  in  the 
males  only  of  the  Australian  Pro^tomus,  while  the  same  is  also 
possibly  true  of  a  new  Indian  genus,  NothognatJms  (fig.  77). 

The  false  mandibles  vary  considerably  in  their  form,  but  they 
are  of  no  value  for  purposes  of  classification,  often  differing 
markedly  in  closely  allied  species ;  they  are  usually  less  de- 
veloped and  more  readily  deciduous  in  the  females,  and  are  a 
conspicuous  feature  of  the  rostrum  in  the  pupal  stage.

b,  Mylloccrus  discolor,  Boh. ;  c,  Aati/cus  lateralis,  F. 

It  is  generally  assumed  that  the  newly  emerged  insect  utilises 
these  organs  for  breaking  its  way  out  of  the  cocoon  or  through 
the  soil  beneath  which  it  has  pupated  ;  and  this  conclusion  finds 
support  in  the  fact  that  the  appendages  are  present  only  in  those 
species  that  have  obtuse  mandibles,  the  edges  of  which  are  deep 
vertically  and  meet  like  a  pair  of  pincers,  being  more  suitable 
for  crushing  than  for  cutting.  M.  P.  Lesne  has  recorded  an 
observation  in  this  connection  made  by  himself  on  newly  emerged 
examples  of  a  European  species,  Exomias  pellucidus,  Boh.  (Bull. 
Soc.  Ent.  Erance,  1899,  p.  143): — "Propped  up  in  its  sub- 
terranean chamber,  the  weevil  opens  its  mandibles  and  seizes  a 
particle  of  earth  between  the  long  appendages  ;  it  then  inclines 
its  head  beneath  its  thorax  and  deposits  the  particle  between  its 
legs,"  this  operation  being  continued  so  that  it  gradually  works 
its  way  up  to  the  surface. 

In  the  majority  of  the  PHAyEEOGNATiii  the  mandibles  are  strongly

bidentate  internally  (fig.  2),  but  in  the  species  with  a  slender 
rostrum  they  are  prominent,  flattened,  triangular  and  pointed 
at  the  apex.  In  the  EHYXcmxix.E  they  are  toothed  on  the 
external  edge,  while  in  several  Jarge  Cala:sdrin.5;  the  outer  sur- 
face is  produced  into  a  long  recurved  process  (tig.  6),  which  at 
first  sight  might  be  thought  to  belong  to  the  gena.  The  Bala- 
niniNjE  present  a  very  remarkable  anomaly  in  the  structure  of 
the  mandibles,  for  tlie  condyles  are  dorsal  in  position,  instead 
of  at  the  sides,  so  that  the  mandibles  work  vertically  side  by 
side,  instead  of  being  horizontal  and  opposed. 

Antenna'. — The  antennae  may  be  situated  anywhere  between 
the  base  and  the  apex  of  the  rostrum  ;  they  are  generally  in- 
serted at  the  side,  but  if  on  the  upper  surface,  they  will  always 
be  found  at  the  apex  (commonly  so  in  the  Adelognathi),  whereas 
in  the  comparatively  few  cases  in  \\  Inch  they  are  placed  beneath, 
they  are  always  well  behind  the  middle. 

There  are  two  well-marked  types,  namely,  those  in  which  the 
first  joint  is  very  long  (being  then  known  as  the  scape),  so  that 
the  a!itennfe  are  elbowed,  or  geniculate  ;  and  those  in  which  this 
joint  is  short,  the  whole  organ  being  straigiit  or  gradually  curved. 
The  use  of  this  character  for  one  of  the  main  divisions  of  the 
family,  which  was  originally  suggested  by  Schonherr  and  recently 
adopted  by  Kolbe  (Arch."  Xaturges.  1901,  Beiheft,  p.  143),  is 
very  unsatisfactory,  as  it  leads  to  an  obviously  unnatural  grouping 
of  the  genera. 

Lacordaire  considered  that  the  normal  number  of  joints  in  the 
antenna  is  12;  but,  as  he  himself  admitted,  one  would  be  quite 
justitied  in  regarding  the  very  small  terminal  joint,  whicli  is 
usually  indistinct  and  very  often  indistinguishable,  as  being  merely 
a  false  joint,  like  that  which  so  often  occurs  among  the  Chry- 
SOMELIB.B,  Cerambycid^,  Elateihu.t;,  etc.  The  antenna  is 
usually  treated  as  consisting  of  three  portions: — (1)  the  scape, 
consisting  only  of  the  basal  joint ;  (2)  the  funicle,  which  normally 
comprises  7  joints,  the  number  varying  from  4  to  8;  and  (3)  a 
terminal  club,  composed  normally  of  3  or  4  joints. 

The  scape  varies  greatly  in  length,  but  even  in  the  species 
with  straight  antennae  it  is,  with  very  rare  exceptions,  longer 
than  the  first  joint  of  the  funicle.  In  the  great  majority  of 
Abelognathi  the  scape  reaches  beyond  the  front  margin  of  the 
eye,  whereas  this  is  rarely  the  case  in  the  species  with  a  long 
rostrum.  The  most  notable  exception  to  the  latter  rule  is  to  be 
found  in  an  Australasian  group  of  Cryptorohynchin.e,  the 
Mecistostybini  ;  in  the  males  of  a  Mecomastiix  from  New 
Caledonia  the  scape  is  at  least  as  long  as  the  whole  insect  and 
may  be  four  times  as  long. 

In  by  far  the  greatest  number  of  species  the  funicle  is  com- 
posed of  7  joints,  but  those  in  which  there  are  only  6  are  fairly 
numerous,  even  if  we  exclude  the  forms  in  which  the  7th  joint 
is   partly  annexed  to   the  club,  nearly  all  of  them  occurring  in 


INTRODUCTION. 


IL 


the  Phaxerognatiii.*  The  forms  in  which  the  funicle  is  o- 
jointed  are  much  less  numerous,  namely,  Mecinvs  (Erirrhinin.t:), 
the  CioNiN.E,  the  Gymnetrin.e,  luid  the  Pentauthriues  (Cosso- 
NiN.i:).  An  8-jointed  funicle  is  still  less  common,  having  been 
recorded  only  in  the  following  genera  : — Ancliomis,  Cylas, 
Myrmackehis  and  Pterocolus ;  Lacordaire  adds  also  the  African 
genera  Ctenomerus  and  Am2)hiboIocori/nus,  but  it  seems  to  be 
more  reasonable  to  regard  these  insects  as  having  6  and  5  joints 
in  the  funicle  respectively,  with  a  loosely  3-jointed  club.  The 
only  genus  which  exhibits  a  4-jointed  funicle  is  the  widely  dis- 
tributed Dn/ojihihorus  (Cossoxin.t:),  which  is  also  remarkable  in 
having  5-jointed  tarsi.  In  certain  genera  of  Cleonin^  it  is 
difficult  to  state  precisely  the  number  of  joints  in  the  funicle, 
as  these  are  so  regularly  widened  towards  the  club  that  it  is  not 
easy  to  say  where  the  "latter  begins.  The  same  applies  to  the 
Belin.e,  in  which  there  is  no  club  whatever. 

The  joints  of  the  antennal  club  are  normally  very  closelv  fitted 
togetlier  so  as  to  form  a  compact  knob,  but  in  certain  subfamilies, 
such  as  the  Atxelabin^,  the  articulations  are  well  marked,  and 
this  is  even  more  pronounced  in  the  Ehynchitin.e,  Awhile  in  a 
few  genera,  such  as  the  two  mentioned  above,  Ctenomerus 
(Erirrhinin.e)  and  Amphiholoeonjnus  (Cionin^),  the  joints  are 
quite  as  free  as  those  of  the  Brenthid  club.  There  is  also  often 
a  marked  tendency  in  the  opposite  direction,  for  in  the  Bracht- 
CERiN.E,  Calandrin.e,  SiPALiN.i:,  etc,  only  the  first  joint  is  fully 
developed,  the  others  being  more  or  less  telescoped  into  it.  In 
Ci/las  and  in  several  genera  of  African  Ithyporin.e  the  club  is 
solid  and  without  any  Trace  of  articulations.  Among  the  Cal- 
ANBRiN.E  it  frequently  assumes  a  hatchet-shaped  form,  and 
occasionally  (C'frc('(?oofr?(s)  differs  markedly  in  the  two  sexes.  In 
some  of  the  long-necked  species  of  Apodenis,  also,  the  apical  joint  of 
the  male  has  a  curved  appendage  which  is  not  present  in  the  female. 

Head. — The  head  is  globular  and  set  well  into  the  prothoracic 
cavity,  but  in  several  groups,  principally  those  having  straight 
antennse,  such  as  Apionin.^,  Cyladin.^,  Ehynchitin.e,  Belin.e, 
etc.,  it  is  prolonged  into  a  short  neck  behind  the  eyes,  while  in 
Apoderus  it  is  extravagantly  lengthened  in  the  males  of  some 
species  and  there  is  a  deep  constriction  near  its  base  in  both 
sexes,  as  in  the  BnENxmnyE. 

There  is  considerable  diversity  in  the  shape  and  position  of 
the  eyes.     In  the  Adelognathi  they  are,  on  the  whole,  relatively 


*  The  following  are  tlie  genera  and  groups  in  which  I  have  noted  a  (i- 
jointed  funicle  : — ^Vicrocerns  and  Ejjisiis  (Braciiycerin.e),  Binomorphus,  some 
EiiYTniiiiUMN.E.  the  Amycterin.e,  some  Riiyparosomin.e,  the  Litiuxix.e,  a 
few  MoLYTiN.E,  iiwo5/?<s  (HYPEiiiN.E),  Aterpus  (Aterpin.e),  some  Ekirkiiinin.e,

small,  being  always  shorter  vertically  than  the  depth  of  the 
rostrum  (fig.  1,  b,  d),  while  in  the  Phanerognaxhi  this  is  very 
rarely  the  ease.  In  the  former  section  there  are  two  fairly  well- 
marked  types  of  eyes,  which  are  correlated  with  the  development 
of  the  postocular  lobe  on  the  front  margin  of  the  prothorax. 
"When  the  lobe  is  absent,  the  eyes  are  rounded  or  short  oval  and 
usually  convex,  sometimes  being  very  prominent,  as  in  the 
African  Podionops  and  Ectatopsides  and  in  some  Indian  species 
■of  Dereodus.  When  the  lobe  is  present,  it  frequently  covers  a 
portion  of  the  eye  when  the  head  is  retracted,  so  that  in  these 
cases  the  eye  is  more  or  less  flattened  and  it  is  apt  to  be  longer 
vertically  and  somewhat  pointed  below.  In  some  Tanyrrhyn- 
■CHIN.5;  the  eyes  assume  a  very  remarkable  position,  being  placed 
close  together  on  the  upper  surface  of  the  base  of  the  rostrum. 
In  certain  groups  of  which  the  species  run  about  fairly  actively 
on  tree-trunks  and  leaves,  such  as  the  Zygopin.i;,  the  eyes  meet 
or  are  closely  approximated  on  the  upper  surface  of  the  head, 
of  which  they  occupy  the  greater  part  ;  on  the  other  hand,  in 
the  Calandeix.t:  and  some  allied  groups  the  eyes  nearly  meet 
on  the  lower  surface  and  are  widely  separated  above  (fig.  1,  e), 
while  in  some  Rhina  (Sipalix^e)  they  occupy  the  whole  of  the 
front  part  of  the  head,  meeting  above  and  below.  I  know  of 
only  one  exception  to  the  rule  that  the  eyes  are  bare,  namely, 
•a  recently  described  South  African  genus,  AncJionocranus 
(Erirriiinin.Ti),  whicl>  has  numerous  erect  scale-like  setie  between 
the  coarse  facets.  A  number  of  genera  are  known  in  which 
the  eyes  are  mucli  reduced,  or  even  entirely  absent,  especially 
among  the  Cossoxi?s^je. 

Frothorax. — Reference  has  already  been  made  to  the  general 
consolidation  of  the  sclerites  of  the  prothorax,  and  another  out- 
standing feature  of  this  segment  is  the  absence  of  the  sharp 
carina  separating  the  dorsal  from  the  lateral  surfaces,  which  is 
so  common  in  the  Coleoptera.  The  only  exceptions  are  to  be 
found  in  two  American  genera,  Oxycorynus  and  Fterocolus,  in 
which  this  carina  is  well  defined.  The  presence  or  absence  of  a 
lobe  on  the  anterior  margin  of  the  prothorax  just  below  the  eye 
affords  a  useful  systematic  character,  as  also  does  the  relative 
position  of  the  front  coxal  cavities.  Lacordaire  used  the  se- 
paration of  the  front  coxse  as  the  essential  character  for  a  very 
large  group  of  Piianerogitathi,  but  he  himself  recognised  that 
this  was  the  weakest  spot  in  his  ^^•hole  system,  and  the  excep- 
tions are  so  numerous  that  his  arrangement  in  that  section  will 
certainly  need  radical  modification.  But  considerable  taxouomic 
value  attaches  to  tlie  various  forms  of  the  deep  pectoral  channel 
which  is  possessed  by  the  Crypxoerhynchin.t:  for  the  reception 
of  the  rostrum.  This  may  be  confined  to  the  presternum,  and 
on  the  other  hand  it  may  extend  as  far  as  the  metasternum, 
while  in  one  South  American  genus  (Panolcus)  it  actually  reaches 
the  end  of  the  abdomen. 

Elytra. — The  elytra  are  always  strongly  chitinised  and  never 
remarkably  shortened,  though  in  many  groups  the  pygidium  is 


INTRODUCTION.  1 3" 

freely  exposed.  In  the  vast  majority  of  species  they  bear  im- 
pressed lines,  or  striae,  containing  rows  of  punctures,  the  normal, 
number  of  these  strice  being  10,  of  which  the  outer  or  tenth*  is 
often  visible  only  in  the  basal  half.  The  presence  of  a  true 
shoulder  often  affords  a  useful  distinction,  and  it  is  very  con- 
stantly correlated  with  the  possession  of  fully  developed  wings. 
Leconte  has  used  for  some  of  his  lai'ger  subdivisions  of  the  familv 
a  character  which  has  been  quite  neglected  by  other  authors, 
namely,  the  presence  or  absence  of  a  strong  carina  near  the 
outer  margin  of  the  elytra  on  their  under  surface,  which  evi- 
dently engages  with  the  concealed  chitinised  margin  of  the 
ventral  segments,  thus  giving  much  greater  rigidity  to  the  body. 
As  he  has  employed  it,  the  character  is  subject  to  exceptions 
which  render  it  distinctly  unsatisfactory,  but  there  can  be  little 
doubt  that  it  will  furnish  some  useful  distinctions  when  it  has 
been  examined  in  a  larger  number  of  genera.  In  many  wing- 
less species  the  elytra  are  fused  together  along  the  suture,  and 
in  some  cases  (BkachycerijSM)  they  are  more  or  less  soldered 
laterally  to  the  sides  of  the  sternum. 

Wings. — The  venation  of  the  hind  wings  in  the  Curculionid.e 
has  not  been  sufficiently  studied  to  enable  it  to  be  utilised  for 
purposes  of  classification,  though  it  will  probably  yield  interestnig 
results  when  more  fully  investigated.  The  mere  presence  or 
absence  of  wings  is  a  character  of  unequal  reliability.  In  vai'ious 
genera  there  are  both  winged  and  wingless  species,  but,  on  the 
other  hand,  the  absence  of  wings  is  frequently  correlated  with 
terrestrial  habits,  which  are  often  characteristic  of  deiinite  groups 
of  genera.  Some  authors  have  divided  the  Adelognathi  into  two- 
primary  sections  on  this  character,  but  the  result  is  certainly 
unsatisfactor}',  as  two  heterogeneous  assemblages  are  formed, 
while  obviously  related  species  are  widely  separated.  But  for 
minor  divisions  this  distinction  is  probably  valid. 

Lef/s. — The  femora  are  rarely  linear,  being  usually  more  or  less 
clavate  or  dilated  in  the  distal  half  and  often  bearing  a  tooth  on 
the  under  surface.  In  only  two  genera  containing  small  or 
minute  species,  Rhyncluenus  (Orchestes)  and  llliamphus,  are  the 
insects  able  to  jump,  and  the  hind  femora  are  consequently 
thickened.  The  tibiae  are  frequently  armed  with  spurs  at  the 
apex ;  when  tliere  is  a  spur  or  mucro  at  the  inner  angle,  the 
tibia  is  described  as  mucro nate  ;  and  when  the  outer  angle  is 
produced  so  as  to  form  a  curved  hook,  it  is  called  unguiculate. 
The  tarsi  are  frequently  attached  to  the  tibiae  in  a  truncate  area 
at  the  apex  of  the  latter,  which  is  usually  very  oblique  ;  this 
area  is  known  as  the  corbel,  and  the  forms  which  it  assumes  in 
the  hind  tibiae  are  of  considerable  systematic  importance. 

The  tarsi  are  ap])arently  4-jointed,  except  in  Drjiophthoms,  in 
which  they  are  distinctly  5-jointed,  but  in  many  cases  traces  of 


*  The  intervals  are  also  nmiibered  outwards,  the  space  between  the  suture 
and  the  first  stri;\i  beiug  the  first  iuterral. 


14  CURCULIOXID,!;. 

■the  missing  joint  can  be  observed  at  the  base  of  the  nominal 
fourth  joint.  Again  in  a  few  genera — Anoplus  (Europe),  Dia- 
bathrarms  (Africa),  Aonychus  (Australia)  and  Atclicus  (Australia) 
— the  latter  joint  is  entirely  absent,  the  third  being  broadly 
dilated,  but  not  bilobed  as  usual.  For  the  most  part  the  third 
joint  is  dilated  and  bilobed,  and  lu  such  cases  it  is  clothed 
beneath  with  a  spongy  covering  of  dense  short  adhesive  hairs. 
In  the  purely  terrestrial  forms  (the  extreme  paucity  of  which 
is  a  striking  feature  of  the  Curculionid  fauna  of  India)  this  joint 
is  not  or  but  slightly  broader  than  tlie  others,  and  the  tarsus  is 
then  clothed  beneath  with  longer  non-adhesive  hairs  or  with 
stiff  bristles.  Such  slender  tarsi  are  also  characteristic  of  the 
few  genera  of  aquatic  weevils  {Ba</ous,  IJi/di-onomus,  Ephimerojyus), 
as  well  as  of  the  CossoNix,!.  The  structure  of  the  claws  is  of 
much  systematic  value.  In  the  normal  condition  they  are 
capable  of  independent  movement,  but  are  always  more  or  less 
closely  approximated,  being  then  described  simply  as  free  ;  in  a 
great  many  groups  they  are  fused  together  at  the  base,  and 
sometimes  to  well  beyond  the  middle,  being  then  called  connate  ; 
frequently  they  are  more  or  less  separated  at  the  base  and  placed 
at  a  wide  angle,  when  they  are  known  as  divaricate;  in  a  few 
cases  there  is  only  a  single  claw  —  Atmetoni/chus  (Indian), 
Holowichus  (Madagascar),  BarilejHoii  (American),  Bmrhyhamvs 
(American),  Haploiujx  (Australian),  JIunomjchus  (Holarctic) ; 
•occasionally  the  claws  are  armed  with  a  tooth,  and  more  rarely 
they  are  cleft. 

Abdomen. — The  number  of  abdominal  segments  requires  further 
investigation.  Leconte  and  Horn  considered  that  the  normal 
number  of  tergites  was  seven,  but  that  in  all  the  subfamilies 
except  Ehinomacerin.t;,  EnYNCHiTiNyE,  Attelabix.15,  Apionin.i: 
and  Cala^'driNuE  the  males  had  the  seventh  tergite  divided  into 
two,  while  the  females  had  only  the  normal  seven.  The  validity 
of  this  interpretation  appeared  doubtful  when  it  was  discovered 
that  in  African  species  of  several  genera  of  Adelognathi  {Pohj- 
■cleis,  Neocimbus,  Strophosomus)  the  females  have  a  distinct  eighth 
tergite,  almost  as  large  as  that  of  the  male,  while  in  two  other 
genera,  Proscephaladeres  and  Eremnus,  and  in  some  Indian 
Episonms,  this  tergite  was  distinctly  visible,  though  for  the  most 
part  withdrawn  beneath  the  seventh.  Further  dissections  render 
it  highly  probable  that  in  every  case  where  there  are  only  seven 
tergites  visible  a  concealed  anal  one  will  be  found,  the  number 
having  been  ascertained  to  be  the  same  (namely,  eight)  in  both 
sexes  of  all  the  species  examined  so  far.  In  the  majority  of 
these  species  I  have  noticed  a  silky  patch  on  each  side  at  the 
base  of  the  seventh  tergite.  They  are  situated  just  beneath  the 
complicated  fold  of  the  wing,  and  it  seems  probable  that  they  may 
serve  as  a  soft  j^ad  on  which  the  delicate  membrane  can  rest 
without  risk  of  damage,  this  view  being  supported  by  the  fact 
that  they  have  not  been  found  in  those  species  in  which  the 
wings  are  reduced  or  absent.  The  shape  and  position  of  these 
patches  may  possibly  yield  good  diagnostic  characters. 


INTRODUCTION.  15 

Oil  the  reiitral  aspect  only  five  segments  are  normally  visible, 
the  two  basal  ones  iiaving  permanently  disappeared.  Lacordaire 
(Gen.  Col.  vi,  p.  12)  mentions  two  genera — Ithyccnis  (North 
America)  and  DicJiotracJielus  (Europe) — in  which  there  is  a  sixtli 
segment.  Leconte  and  Horn  state  that  the  number  is  never 
more  than  five,  the  appearance  of  a  sixth  segment  being  merely 
due  to  the  accessory  tergite  of  the  male  having  been  pushed  into 
a  ventral  position.  While  their  interpretation  may  possibly  be 
correct  in  certain  cases,  the  general  statement  that  there  is 
never  a  true  sixtli  ventral  segment  cannot  be  maintained.  In 
those  genera,  such  as  Neocimhus  and  Pohjdels,  in  which  the 
females  have  a  well-exserted  eighth  tergite,  there  is,  paired  with 
tliis  tergite,  a  strongly  chitinised  sixth  ventral  plate,  which, 
though  normally  concealed,  is  capable  of  being  exserted.  Its 
occurrence  in  this  sex  has  also  been  noted  elsewhere  and  will 
probably  prove  to  be  general. 

In  the  great  majority  of  genera  the  first  two  visible  segments 
(in  descriptions  the  two  vanished  ones  are  not  counted)  are  more 
or  less  soldered  together,  even  though  they  may  appear  to  be 
separated  by  a  superficial  suture,  the  nature  of  this  suture  and 
the  relative  lengths  of  the  intermediate  segments  affording  good 
generic  distinctions.  The  basal  segments  are  entirely  free  in 
only  a  few  subfamilies,  such  as  IIhixomacerin^,  Ehynchitin.e, 
Belin.t;  and  Eurbhynchin.e, 

Superficial  clothing.— As  compared  with  other  Coleoptera,  the 
weevils  are  remarkable  for  the  very  large  percentage  of  forms 
that  are  clothed  with  scales.  In  a  few  subfamilies  all  the  species 
ure  devoid  of  scales,  but  these  are  all  groups  containing  very 
few  genera,  such  as  Attelabin.e,  EHYNcniTiNyE,  Apionin.^, 
Ci-LADiNiE,  Belin^,  TrypetintE,  etc.  In  the  Cossonin.e  and 
Calandrin.4;  the  occurrence  of  scaling  is  a  rare  exception,  many 
species  in  the  latter  subfamily  exhibiting  a  characteristic  pruinose 
covering  ;  while  in  the  Baridix^,  A\-hich  comprises  a  very  large 
number  of  species,  the  great  majority  are  glabrous.  Compara- 
tively little  attention  has  been  paid  by  systematists  to  the  structure 
of  the  scales,  though  these  often  exhibit  good  specific,  and  even 
generic,  characters.  They  vary  greatly  in  shape,  and  are  some- 
times fringed  with  hairs,  while  in  some  groups  (e.  g.  Cleonin.i;) 
each  scale  may  be  split  up  into  a  mere  bunch  of  feathery  filaments. 

In  the  squamose  groups  the  intervals  of  the  elytra  almost 
invariably  bear  more  or  less  regular  rows  of  setae,  which  frequently 
furnish  excellent  specific  characters.  In  certain  pubescent  genera, 
such  as  Lixus  and  Larinus,  the  colouring  is  produced  by  a  coating 
of  a  fine  powdery  substance,  which  is  very  easily  abraded. 
Laboulbene  insisted  that  this  efflorescence  was  of  a  crypto<>-amic 
nature  (Ann.  Soc.  Ent.  France,  1848,  p.  301  ;  1850,  p.  17),  but 
there  can  now  be  but  little  doubt  that  it  is  actually  secreted  by 
the  insects  themselves,  and  Lacordaire  (Gen.  Col.  vi,  p.  417)  and 
others  have  recorded  that  tlie  substance  can  be  renewed  by  the 
living  insects  after  it  has  been  rubbed  off;  in  se\eral  cases  it 
forms  a  regular  pattern.     In  a  few  Eastern  genera  (Alcides  and 


16  CUECULIOyiD^. 

Poepalosomus)  some  of  the  species  are  capable  of  producing  more 
striking  secretions  in  the  form  of  white  wax-like  flocculent  ex- 
crescences, similar  in  character  to  those  of  various  Coccid.e 
and  ruLGORiD.=E. 

Sexual  Dimorphism. 

There  are  comparatively  few  instances  of  very  marked  sexual 
disparity  iu  the  CuRCULioxiD-i),  and  there  should  rarely  be  any 
difficulty  in  associating  the  sexes  of  any  given  species.  In 
certain  genera,  especially  among  the  more  rotund  wingless 
terrestrial  forms,  the  difficulty  lies  in  the  opposite  direction, 
and  in  the  case  of  such  insects  as  Blosyrus  or  Brachycerus  there 
are  often  no  reliable  external  characters  by  which  the  sexes  can 
be  discriminated. 

The  sexual  distinction  that  is  perhaps  of  the  most  general 
occurrence  is  to  be  found  in  the  lirst  ventral  segmeut,  -which  is 
more  or  less  strongly  impressed  m  the  middle  in  the  male,  while 
in  the  female  it  is  flat  or  even  shghtly  convex ;  but  to  this  there 
are  very  numerous  exceptions.  In  those  forms  that  have  a 
comparatively  short  rostrum,  this  organ  is  rarely  different  iu 
the  two  sexes  (though  occasionally  the  geuae  have  a  lateral 
process  iu  the  males),  but  the  females  are  generally  larger  and 
liave  the  sides  of  the  elytra  more  strongly  rounded,  while  tlie 
fifth  ventral  segmeut  is  frequently  more  pointed  in  this  sex. 
When  the  rostrum  is  elongate,  it  nearly  always  exhibits  good 
sexual  characters.  If  there  is  any  difference  in  size,  that  of  the 
female  is  longer  and  more  slender ;  while  when  the  length  is 
equal,  the  rostrum  of  the  male  is  nearly  always  more  coarsely 
punctured  and  the  punctures  extend  nearly  or  quite  up  to  the 
apex,  whereas  in  the  female  the  apical  half,  or  more,  is  very  finely 
punctate  or  even  quite  smooth. 

The  inequality  in  the  length  of  the  rostrum  is  most  marked  in 
a  South  African  species  of  Antliarrliinus  that  oviposits  in  the 
cones  of  Cycads  ;  in  the  male  this  organ  is  about  as  long  as  the 
head  and  prothorax,  while  in  the  female  it  is  nearly  three 
times  as  long  as  the  whole  body.  In  some  Calaudrine  genera 
{Protocerius,  Ehijnchojjhorus)  the  rostrum  of  the  male  is  dis- 
tinguished by  a  row  of  tubercles  or  a  crest  of  hairs  on  its  upper 
surface,  while  in  Ehina  it  has  a  dense  fringe  of  long  hairs  beneath. 

Differences  in  tlie  form  of  the  antennae  are  not  rare.  Tor 
example,  in  Eurrhynclms  (Australia)  and  Cylas  the  solid  club  is 
uiuch  longer  in  the  male  ;  in  Gercidocerus  the  club  is  enormously 
elongate  transversely  in  the  male,  so  that  the  anteuna  has  the 
sliape  of  a  pickaxe  ;  in  some  Indian  Apoderus  the  terminal  joint 
of  the  male  is  produced  into  a  curved  process  ;  and  in  Mecomastyx 
(New  Caledonia)  the  scape  of  the  male  may  be  anything  from 
t)  to  12  times  as  long  as  that  of  the  female. 

There  are  certain  instances,  as  in  the  very  large  Indian  weevils 
of  the  genus  Cyrtotrachelus,  in  which  the  front  legs  of  the  males 


IXTBODUCTIOI^.  17 

are  uinisually  elongated,  and  in  various  genera  of  Crypto- 
RRHYxciiiN.Ti;  the  front  tibise  or  tarsi  may  be  fringed  with  long 
hairs  in  this  sex  ;  in  certain  OTiORRKYSCiiiNJE—S'i/stutes  (Africa)^ 
Cyrtozemia  (India) — the  bind  or  middle  tibias  are  often  stronglv 
curved  or  tootiied  in  the  males. 

One  of  the  few  cases  in  which  the  two  sexes  have  been  re- 
garded as  distinct  species  is  the  African  Polycleis  lonc/icornis, 
Fhs. ;  not  only  is  the  colouring  strikingly  diflerent,  "but  the 
shape  of  the  prothorax  is  quite  dissimilar,  and  the  antennae  are 
much  longer  in  the  male.  Another  remarkable  sexual  character 
is  the  long  spine  which  projects  forwards  on  each  side  of  the 
prosternum  in  some  Qentrinus  (America)  and  Mecojms ;  and  the 
hairiness  of  the  males  in  Hypomeces  (India)  is  an  uinisual  form 
of  dimorphism.  Tlie  reason  for  the  extraordinarily  elongate 
liead  in  the  males  of  some  Apodenis  is  by  no  means'  clear,' but 
the  two  hooks  at  the  apex  of  the  tibia  in  the  female  (the  male 
having  only  one)  is  doubtless  connected  with  her  leaf-rolling  liabits. 

StriduJation. 

The  stridulatory  apparatus  in  Curculioxid^  has  received  but 
little  attention,  and  in  1900  Dr.  C.  J.  Gahan  briefly  summarised 
what  was  known  on  the  subject  (Trans.  Enfc.  Soc.  Lond.  1900, 
pp.  449-451).  So  far  as  has  been  ascertained  at  present,  these 
organs  are  confined  to  the  Hylobiin^,  Cry^ptorrhyxchin^, 
CEUTHORRHTNCHiNiE,  and  souie  allied  groups.  In  all  the  cases' 
known  to  Dr.  Gahan  the  soui^d  is  produced  by  the  rubbing  of 
the  pygidium  or  propygidium  against  the  apex  of  the  elytra,  and 
this  may  be  effected  in  two  ways:— (1)  the  files  may  be  situated 
on  the  under  surface  of  the  elvtra,  along  the  apical  portion  of 
the  suture,  the  scrapers  consisting  of  a  number  of  granules  on 
the  pygidiinn  ;  or  (2)  the  files  may  be  placed  on  the  pj'gidiuni^ 
while  an  oblique  ridge  near  the  apex  of  ench  elytron  serves  as  a 
scraper,  against  which  the  file  is  rubbed  by  a  u'lovement  of  the 
abdomen.  In  some  species,  such  as  the  European  Cryptorrluin- 
chus  IcqMtthi,  L.,  tlie  stridulating  mechanism  is  found  in  the 
male  sex  only,  the  files  being  placed  on  the  elytra  ;  in  others, 
belonging  to  the  genera  PlintJms,  Accdles,  Mononychus,  etc.,  the 
organs  occur  in  both  sexes,  the  files  being  again  on  the  elvtra; 
while  in  a  third  group,  first  recognised  by  Dr.  Gahan,  both  sexes 
are  able  to  stridulate,  but  the  files  are  on  the  elytra  in  the  males 
and  on  the  pygidium  in  the  females.  To  the  last-named  group 
belong  certain  species  of  the  following  Indian  genera :  Crypto- 
rrhynchus,  Campton^hinus,  Gasterocercus  and  Ectatorrliinus. 

Larva'. 

Despite  their  undoubted  economic  importance,  extremely  little 
is  known  about  the  early  stages  of  Indian  Curcclionid.e,  and, 
indeed,    this    applies    to    the    family   as   a    whole;    for   even    in

CURCULIONID^. 


Europe  and  North  America,  where  alone  tlie  subject  has  received 
any  considerable  attention,  the  species  whose  larvae  and  pupfe 
have  been  described  form  a  very  small  percentage  of  the  whole. 

The    outstanding    feature    of    Curculionid  larvse   is   that    they 
are,  without  exception,  legless,  and  their  general  appearance  is

remarkably  similar  even  in  the  most  widely  separated  subfamilies 
((/.  figs.  8,  9,  10).  In  those  species  which  lead  a  more  or  less 
stationary  existence  (and  this  is  true  of  the  great  majority  of 
the  known  forms)  the  larvae  are  rather  stout,  with   the   body

distinctly  curved  and  only  slightly  narrowed  towards  the  tail 
end.  The  head  is  entirely  exserted,  rounded  and  fully  chitinised, 
being  of  a  testaceous  colour,  while  the  rest  of  the  body  is  greyish 
white  or  ivory  white,  except  in  the  few  species  that  are  external 
feeders,  in  which  the  body  has  a  certain  amount  of  green  or

ibrovvn  pigment.  The  inamlibles  are  well  developed  and  are  often 
obtusely  toothed ;  the  maxillae  are  almost  contiguous  to  the 
Jabium  and  have  a  short  angular  internal  process  which  carries 
the  small  palpus,  composed  ot  two  or  three  joints  ;  the  mentum 
is  large  and  scarcely  separable  from  the  labium,  being  furnished 
with  two  very  short  two-jointed  pal])i.  The  antennae  are  usually 
absent,  being  represented  merely  by  a  small  prominence  near  the 
base  of  the  mandible  bearing  a  single  hair ;  but  occasionally  a 
minute  two-jointed  antenna  is  present.  The  larvae  are  normally 
blind,  but  the  external  feeders  have  one,  two  or  three  ocelli. 
The  three  thoracic  segments  are  rather  more  developed  than  the 
abdominal  ones,  and  bear  only  a  single  pair  of  spii*acles,  which 
are  situated  on  the  prothorax,  though  occasionally  they  occur  on 
the  mesothorax.  Of  the  nine  abdominal  segments,  there  is  a 
pair  of  spiracles  on  each  of  the  first  eight ;  in  the  Calandrtn^e 
■alone  is  there  a  cbitinous  termination  to  the  ninth  segiuent.

In  the  curved  sedentary  larvae  the  structure  of  the  body  seg- 
ments is  in  no  way  remarkable,  but  in  those  forms  which  inhabit 
galleries  in  the  stems  of  plants  (e.g.  Lixus)  or  make  mines  in 
the  parenchyma  of  leaves  (e.g.  Rliyncluenus)  the  body  is  usually 
hairy  and  the  segments  frequently  bear  callosities  or  tubercles 
(both  dorsally  and  ventrally)  set  with  short  bristles,  \\iiich  enable 
the  larva  to  move  backwards  and  forwards  in  its  galleiy.  These 
larvae  are  never  curved  and  generally  they  are  more  narrowed 
posteriorly. 

Hahils  and  Life- Histories. 

So  far  as  is  known  at  present,  all  Curculionid.^,  both  in  the 
larval  and  adult  stages,  feed  only  on  vegetable  substances;  but 
Mr.  C.  F.  C.  Beeson,  Imperial  Forest  Zoologist  at  Dehra  Dun,

20  CUKCULIONID.i:. 

informs  ine  that  lie  has  reasons  to  suppose  that  tlie  very  small 
cylindrical  weevils  of  the  genus  Phamomenis  are  predaceous  on 
bark-beetles  of  the  family  Scolytid.e.  The  slender  rostrum  and 
minute  mandibles  of  these  weevils  seem  ill-adapted  to  such  a 
diet,  and  judgment  on  the  question  ma}^  well  be  suspended  until 
definite  evidence  is  forthcoming. 

In  the  adult  stage  the  majority  of  weevils  frequent  the  foliage 
of  ti'ees,  slirubs  and  herbaceous  plants,  comparatively  few  of 
them  being  especially  attracted  to  flowers.  Another  large  section, 
containing  representatives  of  many  subfamilies,  are  mainly  terres- 
trial in  tlieir  habits.  In  this  group,  -which  is  but  poorly  repre- 
sented in  the  Indian  fauna,  the  species  are,  almost  M"ithout 
exception,  dull-coloured  and  have  lost  the  power  of  flight.  In 
the  purely  terrestrial  forms  the  tarsi  have  partly  or  completely 
lost  the  adhesive  spongy  pads  on  their  lower  surface;  many  of 
the  others  only  pass  the  day  on  the  ground  for  purposes  of 
concealment,  ascending  their  food-plants  at  night  to  feed.  Some 
half-dozen  European  genera  have  been  described  in  which  the 
species  are  entirely  subterranean  in  their  habits,  and  in  all  of 
these  the  eyes  are  absent  or  quite  rudimentary ;  doubtless  similar 
forms  will  be  found  to  occur  in  India.  A  few  genera  of  weevils 
are  truly  aquatic,  the  larval  stage  being  passed  in  the  stems  of 
water-plants  beneath  the  water.  Two  such  genera  have  been 
recorded  from  within  our  limits,  namely,  Bagous  and  Litodacti/lvs  ; 
the  species  of  the  former  are  not  able  to  swim,  but  merely  drift 
through  the  water  if  they  lose  their  hold  on  the  food-plant, 
whereas  the  species  of  Liiodactylus  use  their  legs  for  swimming, 
although  these  are  not  in  any  way  specially  modified  for  the 
purpose.  Among  the  Cossonin^  the  majority  of  the  species  are 
to  be  found  under  bark,  a  mode  of  life  which  is  very  unusual  in 
other  subfamilies.  It  is  somewhat  remarkable,  seeing  the  diversity 
of  their  tastes,  that  no  species  of  this  family  appear  to  have  been 
found  living  in  fungi.  A  very  few  truly  myrmecophilous  and 
termitophilons  weevils  have  been  described,  but  hitherto  none 
has  been  recorded  from  India. 

Taken  as  a  whole,  the  colouring  of  weevils  is  distinctly  sombre, 
greys  and  browns  being  in  overwhelming  preponderance.  "Witli 
few  exceptions  the  gayer  colours  and  patterns  are  due  to  the 
scaly  covering,  the  integument  being  usually  black  or  brown, 
though  sometimes  yellowish  in  the  forms  that  frequent  flowers. 
Outside  of  the  Rhtjsxhitin^  brilliant  metallic  colouring  of  the 
integument  is  scarcely  to  be  found  except  among  the  Baeidin.i: 
and  their  immediate  allies  ;  among  the  Calandkin.^:  I  know  of 
only  a  single,  apparently  undescribed,  species  from  Singapore 
in  which  the  elytra  are  of  a  metallic  green  colour.  In  spite  of 
this  general  tendency  to  sobriety  in  colour,  the  Curculionid^ 
have  produced  some  of  the  most  beautiful  creatures  in  the  insect 
world,  among  which  may  be  mentioned  the  large  i<\iy -blue  JiJuphohts 
of  Papua;  the  PacJnp'rhi/nchus  of  the  Philippines,  adorned  with 
strange  patterns  glittering  with  green,  blue,  gold  and  copper; 


IXTRODUCTION.  21 

the  resplendent  Cephas  aiul  Bnthnus  (popularly  known  as  Diamond 
Beetles)  of  Brazil;  and  the  bejewelled  Cratopus,  peculiar  to  the 
islands  of  the  Indian  Ocean. 

'The  comparative  paucity  of  conspicuously  marked  species  pro- 
bably indiL-ates  a  general  hick  of  qualities  distasteful  to  those 
animals  which  would  be  likely  to  prey  upon  them,  such  as  an 
unpleasant  taste  or  smell,  the  possession  of  which  it  Avould  be 
profitable  to  advertise  by  means  of  conspicuous  coloration.  The 
schemes  of  colouring  are  for  the  most  part  undoubtedly  j)'"0: 
cryptic,  that  is  to  say,  they  harmonise  with  the  natural  sui-rouud- 
iugs  of  the  insect  so  as  to  render  it  inconspicuous  ;  and  this  is 
probably  true  of  the  metallic  green  scaling  which  so  frequently 
manifests  itself  among  the  small  leaf-eating  species  of  many 
different  genera  of  Abelognathi,  but  which,  for  some  reasoii 
that  is  not  obvious,  is  extremely  rare  among  the  species  with  a 
long  rostrum  that  have  similar  habits. 

But  though  they  may  be  deficient  in  active  deterrents  for  their 
enemies,  the  weevils  have  very  widely  adopted  an  effective  passive 
means  of  defence,  namely,  extreme  hardness,  not  infrequently 
accompanied  by  the  presence  of  sharp  spines  on  the  thorax  and 
elytra  which  nuist  render  them  uncomfortable  morsels  for  swallow- 
ing whole.  This  method  of  protection  is  naturally  best  developed 
in  the  larger  wingless  terrestrial  forms.  The  species  of  Pacliy- 
rrhjncJius,  referred  to  above,  are  certainly  extremely  hard  and  may 
possess  other  deterrent  qualities,  and  there  seems  to  be  some 
reason  for  supposing  that  their  striking  patterns  have  a  warning 
significance,  for  they  are  mimicked  Avith  extraordinary  accuracy 
by  certain  Longicorus  of  the  genus  BoUops.  Similarly,  in  other 
parts  of  the  world  various  large  terrestrial  weevils  are  closely 
resembled  by  wingless  Lougicorns  having  similar  habits.  These 
are  the  only  recorded  cases  in  «hich  we  may  reasonably  assume 
that  weevils  have  served  as  models  for  other  insects.  On  the 
other  hand,  no  case  has  yet  been  demonstrated  of  a  weevil 
mimicking  another  insect,  and  this  is  the  more  remarkable  when 
we  consider  what  vast  luimbers  of  CuucT:LIO^'IU.E  there  are  and 
what  extremely  varied,  and  sometimes  fantastic,  forms  they  have 
assumed. 

Most  weevils  are  somewhat  slow  in  their  movements,  and  it 
is  only  among  certain  groups  of  the  Zyuopin^e  with  rather  short 
elytra  and  slender  legs  that  we  find  any  species  that  are  really 
active  ;  these  insects,  when  disturbed,  are  capable  of  taking  to 
flight  quite  as  rapidly  as  tiger-beetles  of  the  genus  Cicindela. 
With  most  species  the  unfolding  of  the  wings  is  a  rather  laborious 
process,  and  no  doubt  it  is  mainly  on  this  account  that  they  have 
so  widely  adopted  the  disconcerting  habit  of  dropping  suddenly 
from  their  food-plant  into  the  herbage  beneath  on  the  slightest 
sign  of  danger.  The  protective  value  of  this  method  of  escape 
is  further  enhanced  by  a  kind  of  behaviour  that  is  more  widely 
prevalent  in  this  family  than  among  other  beetles,  namely,  the 
death-feigning  instinct.     This  is  especially  well  marked  in  those 


22  cuRCULioNii),?:. 

groups,  such  as  the  Cb.YPTOKEHYIS'CHIjS'^  and  CEUTHOREHYKCHINiE^ 

in  which  there  is  a  pectoral  channel  for  the  reception  of  the 
rostrum  ;  with  this  organ  hidden  away  and  the  legs  packed  closely 
together  (the  femora  are  frequently  grooved  to  receive  the  tibiee) 
the  insect  may  readily  be  mistaken  for  a  lump  of  earth,  a  bit  of 
bark  or  a  bird-droppiug.  The  larger  ground-frequenting  species 
when  feigning  deatii  often  lie  with  the  legs  fully  and  stiffly 
extended  in  a  bunch.  As  these  limbs  are  by  no  means  easy  to 
break,  this  attitude  would  render  it  difficult  for  smaller  birds  to 
swallow  them  ;  but  that  it  is  hardly  an  effective  protection  against 
large  birds  may  be  illustrated  by  the  fact  that  1  have  taken  from 
the  crop  of  a  single  South  African  bustard,  among  other  insects, 
65  fair-sized  ground  weevils  belonging  to  1\)  different  species, 
and  evidently  all  of  them  had  been  swallowed  whole. 

It  is  by  no  means  clear  what  is  the  special  function  of  the 
rostrum  in  those  species  in  which  this  organ  is  i-elatively  short 
and  stout,  and  similar  in  the  two  sexes  ;  but  ii!  the  long-beaked 
forms  it  has  been  sufficiently  shown  that  the  slender  rostrum  of 
the  female  is  used  to  enable  her  to  bore  a  hole  into  some  special 
portion  of  the  food-plant  which  is  suitable  for  the  reception  of 
her  eggs.  In  such  species  the  character  may  have  been  first 
developed  in  the  female  and  then  traiisferred  to  the  male  ;  just 
as  in  most  bees  the  pollen-collecting  apparatus  is  partly  de\eloped 
in  the  males,  to  wdiom  it  is  quite  useless,  and  may  even  be 
perfectly  developed,  as  in  Bovihus. 

In  the  ease  of  BuJaninns  it  has  been  definitely  stated  {cf. 
Bargagli,  Bull.  Soc.  Eiit.  Ital.  xv,  1883,  p.  314)  that  the  female, 
after  boring  the  hole,  deposits  the  egg  in  the  orifice  and  pushes 
it  down  to  the  bottom  with  its  rostrum,  which  thus  entirely 
fulfils  the  functions  of  an  ovipositor.  This  statement  has  been 
reitei-ated  by  various  authors,  but  apparently  without  direct 
confirmation.  Tabre  (8ouv.  Entomol.  vii,  p.  115)  has  with  some 
justice  contended  that  such  a  procedure  is  in  the  highest  degree 
improbable,  and  in  the  case  of  Balauinus  eleplias,  Glyl.,  he  has 
sufficiently  demonstrated  that  the  egg  is  deposited  directly  at  the 
bottom  of  the  bore-hole  by  means  of  an  extensible,  membranous 
ovipositor  about  as  long  as  the  rostrum.  It  seeujs  likely  that 
this  will  prove  to  be  the  normal  method  of  ovi position. 

Much  has  been  written  concerning  the  remarkable  habits  of 
the  leaf-rolling  species  of  Bhyvcliiics,  Apoderus,  etc.,  which  are 
well  represented  in  the  Indian  fauna.  The  method  adopted  is  to 
some  extent  conditioned  by  the  size  of  the  leaves  of  the  food-plant. 
"When  these  are  small,  a  whole  leaf,  or  even  more  than  one,  is 
utilised  to  form  the  funnel  or  packet  which  is  destined  to  serve 
at  the  same  time  as  food  and  protection  for  the  larvae  ;  but  more 
often  only  a  portion  of  a  leaf  is  used,  and  the  manner  in  which 
this  is  cut  out  and  folded  appears  to  be  characteristic  for  each 
species.  The  rolls  of  Rhyncliites  are  usually  more  elongate, 
funnel-shaped,  or  cigar-shaped,  while  those  of  Ajjodervs  and 
Atielahns   are    relatively    shorter    and    approximately  cylindricaL 


INTRODUCTION.  23 

No  sort  of  adhesive  appears  to  be  used  in  the  construction  of 
the  rolls,  but  the  curling  of  the  leaves  is  ettected  by  patient  and 
continuous  pressure,  while  they  are  prevented  from  unrolling 
by  an  ingenious  method  of  tucking  in  the  ends  and  the  free 
edge.  lu  every  case  the  \\'eevil  weakeus  either  the  leaf-stalk  or 
the  point  of  attachment  of  the  roll  by  nibbling,  so  that  in  a  few 
days  it  falls  to  tlie  ground,  and  the  mature  larva  eventually  enters 
the  soil  to  pupate. 

It  is  somewhat  remarkable  that  wliile  some  of  the  European 
lihyncJiites,  such  as  li.  hetula%  L.,  have  evolved  this  elaborate 
method  of  providing  for  their  young,  other  species  of  the  same 
genus  have  adopted  a  much  more  simple  procedure ;  for  example, 
the  larvae  of  K.  cupreus,  L.,  and  H.  bacchus,  L.,  feed  merely  ou 
the  pulp  of  certain  fruits ;  those  of  H.  auratus,  Scop.,  live  in  the 
kernels  and  those  of  li.  icosandrice,  Scop.,  and  B.  interpunctatus, 
Steph.,  in  the  buds  of  their  food-plants.  What  may  perhaps  be 
regarded  as  a  first  step  in  the  direcrion  of  a  leaf-rolling  habit  is 
to  be  found  in  certain  OTiORRHrNCiiiN^.  For  example,  the 
common  Indian  Episomus  lacerla,  F.,  lays  a  batch  of  eggs  on  a 
leaf,  which  is  folded  over  so  as  to  cover  them,  the  edges  being 
gummed  together  by  means  of  a  sticky  secretion ;  the  larvae  on 
hatching  gnaw  through  the  leaf  and  drop  to  the  groinid  (Fletcher, 
'  Some  South  Indian  Insects,'  p.  327).  W.  Dwight  Pierce  records 
an  almost  identical  habit  in  the  case  of  the  North  American  Gom- 
psus  auricephalus.  Say  (Proc.  Ent.  See.  Washington,  xviii,  1916, 
p.  7),  and  so  have  Osborn  and  Mally  for  Ei>ica'rus  imbricatus. 
Say  (Proc.  Iowa  Ac.  Sci.  iii,  1896,  p.  207),  and  it  is  probable  that 
this  is  not  an  unusual  method  of  oviposition  in  the  subfamily. 

The  habits  of  the  larvse  are  very  varied,  and  every  portion  of 
a  plant  is  liable  to  attack,  as  the  following  brief  list  will  sliow : — 

Leaves  (exrernally) : — Hi/pera,  Oonlatus,  C'iouvs,  FJu/tohius. 
,,        (rolled)  : — Bhynchites,  Attelahus,  Apoderus. 
,,        (mined) : — lUiynclicenus,  Rhamplms,  Bracliyonyx.

C'ryptoryhynchas,  Calandra,  and  numerous  other  genera. 
Stems  of    Herbaceous  Plants  : — Apion,  LLvtis,   Cenihonhyn- 

chus,  Alcides,  Burls,  etc, 
I'ree-trnnks  : — Hylohivs,  many  CRYPTORRHVNCHiN^ii,  JSpalns, 

Rhyncliophorus,  many  Cossoninje,  etc.

cerus,  many  CleoniNjE,  etc. 
Tubers  : — Cylas,  Euscepes. 

From  the  foregoing  statement  it  will  be  seen  that  the  a  ast 
majority  of  Curculionid  larva)  are  internal  or  subterranean  feeders, 
and  it  is  probable  that  the  loss  of  the  legs  has  resulted  from  their 
sedentary  mode  of  life.  Tlie  adoption  by  a  few  genera  of  the 
liabit  of  feeding  externally  ou  leaves  may  thus  be  a  nu;re  recent

development,  and  it  is  interesting  to  note  that  this  has  not  led 
to  the  reappearance  of  true  legs,  but  that  a  quite  different  mecha- 
nism has  been  evolved  to  enable  tlie  larva  to  maintain  its  position 
and  move  about  the  surface  of  the  plant.  This  is  effected  by 
means  of  a  viscous  secretion  which  covers  the  whole  body  in  a 
very  thin  layer  and  within  which  the  larva  progresses  by  uii- 
dulatory  movements,  often  aided  by  the  presence  of  setigerous 
tubercles  on  the  lower  surface.  A  number  of  different  observers 
have  definitely  stated  that  this  secretion,  or  a  similar  one  used 
by  mauy  genera  for  the  lining  of  their  cocoons,  is  emitted  from 
a  retractile  dorsal  tubercle  on  the  last  segment  just  above  the 
anus  ;  but  recently  T.  Knab  (Proc.  Ent.  Soc.  Washington,  1915, 
p.  154)  has  contended  that  this  statement  is  inaccurate  and 
that  the  substance  is  emitted  from  the  anus  itself.  His  view  is 
in  agreement  with  the  earlier  observations  made  by  Jj'abre  on 
Larinus  maculosus,  Schh.,  and  L.  itrsus,  Y.  (Souvenirs  Entom.  vii, 
pp.  68,  8l)  and  on  Gionus  similis,  Miill.  (op.  cit.  x,  p.  84).  Eabre 
considered  that  the  secretion  was  derived  from  the  Malpighian 
tubes,  and  Knab  agrees  that  this  is  probably  the  principal  source, 
but  that  the  rectal  glands  also  contribute  to  it,  and  possibly  like- 
wise tlie  siirfa,ce  glands  distributed  over  the  body.  When  these 
external-feeding  lai-vse  are  full-grown,  they  construct  from  this 
secretion  cocoons  which  are  attached  to  the  food-plant.  This 
work  is  done  entirely  with  the  mouth,  the  viscous  material  being 
drawn  out  into  silk-like  threads.  In  the  case  of  Hyj^era  the 
cocoons  are  elegant  net-work  structures  of  a  white,  yellow  or 
green  colour,  through  which  the  pupa  can  be  seen  ;  while  those 
of  Gionus  are  bladder-like,  and  in  some  instances  present  a  very 
striking  resemblance  to  the  seed-capsules  of  the  plants  on  which 
they  occur. 

The  movements  of  coleopterous  pupae  are  generally  very  limited, 
but  tliose  of  some  species  of  Hypera  are  capable  of  twisting 
themselves  round  and  round  in  their  cocoons  with  extraordinary 
rapidity  when  disturbed.  This  is  perhaps  done  for  the  purpose 
of  disconcerting  a  possible  enemy,  and  is  comparable  with  the 
habit  of  certain  spiders  of  rapidly  vibrating  their  webs  in  similar 
circumstances.  The  j)upa3  of  some  species  oi  Lixus  are  capable  of 
moving  up  and  down  the  hollow  stems  in  Avhich  they  lie  by  means 
of  their  dorsal  bristles.  In  this  connexion  it  may  be  mentioned 
that  one  of  the  so-called  "  jumpiiig  seeds,"  which  frequentl_y 
attract  attention,  is  due  to  the  movements  of  a  Curculionid  larva, 
Nanophijes  tamnricis,  Gyl.,  which  lives  in  the  seeds  of  a  European 
species  of  tamarisk. 

The  external-feeding  larvse  of  an  i^merican  weevil,  Gcelor/aster 
liiuratus,  Dietz,  are  recorded  by  Knab  {I.e.  p.  155)  as  covering 
themsehes  \\ith  their  own  excreta  for  purposes  of  concealment, 
as  is  done  by  the  larvae  of  the  asparagus  beetles  (Grioceris). 
Some  species  of  the  semi-aquatic  genus  Phytohius  also  show  a 
tendency  in  this  direction. 


INTKODUCTION.  25 

One  of  the  most  interesting  uses  o£  the  anal  secretion  of 
I'urculionid  larva?  is  to  be  found  in  tlie  genus  Larhms.  These 
insects  generally  pass  the  larval  stage  in  the  heads  of  various 
flowers,  usually' of  the  thistle  family,  and  most  of  them  pupate 
in  tlie  same  position.  But  in  Asia  Minor,  Persia  and  Northern 
India  there  are  certain  species,  including  L.  macuhtins,  (xyl.,  and 
L.  syriacus,  Gyl.,  the  larvae  of  which  leave  the  flower-heads  when 
full-grown  and  construct  on  the  stem  of  the  plant  a  nodular 
cocoon,  of  the  size  of  an  olive,  formed  of  a  dirty  white,  chalky 
substance  secreted  by  the  Malpigliian  tubes.  'i'hese  cocoons 
form  an  article  of  commerce  in  the  East,  being  largely  used 
both  medicinally  and  as  a  food.  The  constituent  materials  have 
been  chemicallv  studied  by  Berthelot  (C.  K.  Acad.  Sci.  Paris, 
slvi,  1858,  pp.  1276-79)  and  have  been  found  to  contain  about 
66  per  cent,  of  a  sago-like  subc^tance,  known  as  trehalum,  and 
28  per  cent,  of  a  sugar  allied  to  cane-sugar  and  called  trelialose. 
For  medical  purposes  a  decoction,  is  made  from  the  cocoons 
before  the  weevils  have  matured,  and  this  is  considered  to  be  a 
very  effective  remedy  for  bronchial  catarrh. 

Another  allied  larva  has  also  been  utilised  in  medicine,  namely, 
Kliinocyllus  antiodontahjicus,  Gerbi,  and,  as  its  specific  iiame 
implies,  it  was  sup])osecl  in  certain  parts  of  Europe  to  afford  a 
remedy  for  tooth-ache.  The  bulky  larvte  of  Bhynchojjhoras  and 
allied  genera  are  eaten  as  delicacies  by  the  natives  in  many  parts 
of  the  tropics;  and  in  Australia  A.  M.  Lea  notes  that  the 
larvjB  of  a  species  of  Strongylon-hinus,  which  occur  in  large 
galls  on  Eucalyptus  trees,  are  "eaten  by  tiie  blacks,  and  by 
not  a  few  white  men"  (Proc  Linn.  Soc.  JM.S.AV^  xxii,  1897, 
P-  619).  .  . 

The  gall-making  habit  is  not  an  uncommon  one  m  1  he  family, 
being  found  in  such  genera  as  Sihinia,  Apion,  ]S(moi>liyes,  Gym- 
netron,  Miarus,  CeiitJwrrhyncJius,  Bans,  etc.,  and  the  galls  may 
be  made  on  either  the  stems  or  the  roots  of  the  food-plants. 
Two  European  species  of  Balaninus  are  stated  to  make  use  of 
the  galls  of  certain  Hymenoptera  for  their  own  larva\ 

In  1902  the  Eussian  entomologist,  A.  A.  Silantjev,  made  the 
interesting  discovery  of  the  existence  of  parthenogenesis  in  the 
genus  Otiorrhynclius.  He  was  struck  by  the  fact  that  while  pairs 
of  the  less  common  0.  asphaltinus,  Germ.,  were  frequently 
observed,  this  was  never  the  case  with  0.  turca,  Boh.,  although 
this  is  an  abundant  vineyard  pest  of  which  he  had  seen  hundreds 
of  thousands.  One  thousand  specimens  taken  at  random  proved 
to  be  all  females,  and  subsequently  specimens  were  reared 
parthenogenetically  (Zool.  Anzeiger,  xxix,  1906,  p.  583).  _  Later, 
I.  V.  Vassiliev  showed  the  same  to  be  tlie  case  with  0.  Uyustici, 
L.  (Zool.  Anz.  xxxiv,  1909,  p.  29)  ;  while  in  Italy  in  1913 
Grandi  demonstrated  the  existence  of  the  same  phenomenon  in 
0.  cribncollis,  Gyl.,  of  which  he  states  that  no  male  specimen  is 
yet  known  (Bull".  Lab.  Zool.  Portici,  vii,  19]:?,  p.  17).

Classification. 

Apart  from  Lacordaire's  work,  the  only  serious  attempt  to- 
devise  a  comprehensive  clas.siti cation  of  the  Curculionidie  is  that 
made  by  Leconte  and  Horn  (Gr.  H.  Horn,  Trans.  Amer.  Phil. 
Soc.  1873,  p,  407;  J,  L.  Leconte,  Amer,  Natural,  viii,  July, 
lt74,  pp.  385  and  452;  Leconte  and  Horn,  Proc.  Amer.  Phil. 
Soc.  XV,  1876,  p.  xi),  and  this  was  founded  almost  entirely  on 
a  study  of  New  World  species  only.  The  principal  divisions 
adopted  by  these  two  authors  were  as  follows  :■ —

INTKODUCTION. 


The  priinarv  division  in  this  classiticatiou  has  reference  to  tlie 
number  of  visible  abdominal  tergites  ;  in  the  Allociastra  tlie  males 
are  considered  to  have  «,  and  the  females  7  ;  while  in  the  two  other 
groups  both  sexes  have  7.  Apart  from  the  obvious  inconvenience 
of  utilisiug  for  such  a  purpose  a  distinction  which  is  confined  to 
one  sex,  it  has  been  pointed  out  above  that  there  are  some  im- 
portant exceptions  which  were  unknown  to  Leconte  and  Horn. 
In  various  genera  falling  within  their  Otiobrhynchijd.e  the 
females  have  eight  visible  tergites  and  not  seven  (see  p.  14); 
while  on  the  other  hand  I  have  observed  several  cases  of  males 
with  seven  tergites  only  in  genera  which  would  fall  into  their 
restricted  CukculionidyE,  namel}^  Bcujom,  Metkdma  and  an  uu- 
described  genus  near  Acallojnstas;  and  in  this  group  also  there 
are  two  African  genera  the  females  of  which  have  eight  tergites 
instead  of  seven,  namely,  Omoj^jhonis  and  Nerthops ;  again  in 
examining  half-a-dozen  species  of  Cossonin.e,  which  are  supposed 
to  have  seven  tergites  iu  both  sexes,  I  have  found  an  undescribed 
African  species  which  has  eight  in  the  male,  and  an  Indian 
species,  Brachyiemnus  cq^hahtes,  Est.,  which  has  no  more  than 
six;  finally,  Bedel  has  already  stated  tl-at  the  males  of  Ajnon 
have  eight,  and  not  seven  tergites.  That  the  distinctions  noted 
by  Leconte  and  Horn  are  of  considerable  taxonomic  importance 
cannot  be  doubted,  bub  it  is  clear  that  their  real  significance 
cannot  be  projjerly  appreciated  until  a  much  larger  number  of 
Curculionid  genera  have  been  examined  for  the  purpose. 

The  secondary  character  upon  which  the  three  main  groups 
have  been  founded  is  also  subject  to  serious  exceptions.  Although 
the  Haplogastra  are  stated  to  have  no  inferior  carina  on  the 
elytra,  in  many  of  the  larger  Old  World  lihyncMtes  and  most 
Attelahus  this "  carina  is  distinct,  and  sometnnes  as  strongly 
developed  as  iu  any  other  CurouliojS'ID-E.  On  the  other  hand, 
in  many  wingless  Allogastra,  such  as  Bi/rsops  and  Eremnus, 
the  carina  is  entirely  wanting,  while  in  others,  such  as  Ejnsomus, 
Stropliosonms,  Amphitmetus,  etc.,  it  is  often  quite  rudin)entary. 

In  these  circumstances  it  seems  hardly  probable  that  a  com- 
bination of  the  two  foregoing  characters  would  lead  to  a  reliable 
indication  of  inter-relationstnps,  which  is  the  object  of  all  classi- 
fication, and  this  is  exemplified  by  a  comparison  of  the  two 
divisions  Allogastra  and  Hexerogastra.  Here  we  find  such 
groups  as  the  ApionidJ'.  and  Calakdrid.e  widely  separated  from 
X\\e  CuRCULioNiDyE,  with  which  they  are  closely  related,  a,nd 
intimately  associated  with  the  Anthribid.e,  a  family  with  which 
they  have  obviously  nuich  less  afiinity.  Moreover,  the  proposal 
to  subdivide  Lacordaire's  family  Curculionid.e  into  eleven 
families  is  open  to  the  criticism  that  the  resulting  groups  are 
clearly  quite  disproi)ortionate ;  in  other  words,  the  subdivision 
has  been  carried  either  too  far,  or  not  far  enough. 

As  already  indicated,  it  appears  more  satisfactory  to  retain 
Lacordaire's'conception  of  the  family,  and  for  the  purpose  of  this, 
work  the  main  lines  of  his  classification  will  be  followed. 


.28  CUECULIONID.i:. 

The  two  main  divisions  of  the  i'ainily  may  be  defined  tints  : — 

The  mentiun  comparatively  large  and  Hlliii^-,  or 
nearly  lilling-,  the  buccal  cavity  behind  the 
mandibles,  so  as  to  conceal  more  or  less  com- 
pletely the  maxilla3  and  their  palpi ;  the  siib- 
mentum  not  pedunculate,  or  at  most  Avith  a 
A'ery  short,  broad  peduncle  (fig.  4,  «,  c) Adelognathi. 

The  mentum  comparatively  small  or  narrow  in 
relation  to  the  buccal  cavity  (or  even  com- 
pletely hidden),  and  leaving  the  maxillfe 
entirely  or  very  largely  exposed*;  the  sub- 
nientum  usuidly  with  a  well-marked  peduncle 
supporting  the  mentum  (hg.  3,  b-d)    Phankrognathi. 

The  only  serious  difficulty  wliich  arises  in  connexion  witli 
these  characters  is  in  tlie  genus  Cratojms  (BBACiiYDKEiNyT;),  which 
includes  several  species  that  Lave  a  well  developed  peduncle  to 
the  submentum,  so  that  si  considerable  portion  of  the  maxilla  is 
exposed  ;  but  the  few  Indian  species  are  fully  adeloguathous. 


Division  I.  ADELOGNATIJI. 

No  subdivision  of  this  group  tliat  has  yet  been  proposed  can 
be  regarded  as  really  satisfactory.  The  following  arraiigement 
is  practically  that  of  Lacordaire,  with  the  addition  of  the  Tanykr- 
HYNCHiiS^'E,  which  he  erroneously  placed  among  the  Phanerognaths ; 
also  I  have  followed  Auriviilius  (Iv.  Vet.  Akad.  Handl.  xxi,  no. 
15,  1885)  in  separating  the  Microceein.i;  from  the  Bkachy- 
DEEiNyE.  Although  the  difference  in  the  form  of  the  scrobe  in 
the  latter  subfamily  and  the  Otiouiiiiynchiis^^  is  for  the  most 
part  sufficiently  distinct,  it  must  be  admitted  that  there  are  a 
few  African  genera  whose  position  in  this  respect  is  somewliat 
dubious,  xigain,  the  dividing  line  between  the  OTioiUfHYNcniN.E 
and  EKEMiv'iNiE  becomes  very  line  in  places,  for  the  octilar  lobe 
on  the  prothorax  in  tlie  latter  subfamily  is  often  considerably 
reduced,  while  the  bunch  of  vibrissse  in  a  few  cases  contains  only 
three  or  four  hairs  which  may  readily  be  overlooked,  as  has  been 
done  by  Paust  in  more  than  one  case.  Even  the  mandibular 
scar  is  far  from  constituting  a  i-eally  sharp  character,  for,  as 
Leconte  himself  recognised,  in  certain  sections  it  seems  to  be 
gradually  disappearing;  but  neither  he  nor  subsequent  authors 
appear  to  have  noticed  that  in  the  genus  Brachi/cerus,  «hich 
nominally  has  no  scar,  there  are  not  a  few  African  species  that 


*  In  the  Sn'ALiNyE  (fig.  3,  c)  and  Cryptoder.min.e  tlie  iiioiith-purts  are 
abnormal,  there  being  no  emargination  of  the  siibnieiiLum  ;  the  buccal  cavity' 
is  thus  situated  at  the  extreme  apex  of  the  rostrum  and  is  entirely  tilled  by 
the  mandibles,  so  that  all  the  other  moulli-))arts,  including  the  mentum  and 
niaxilhe,  are  invisible.

have  distinct  mandibular  appendages.  Their  obvious  affinities 
would  make  it  absurd  to  place  these  insects  in  a  different  family 
or  even  subfamily,  and  we  can  only  recognise  that  in  this 
particular  case  the  scar  has,  at  most,  no  more  than  a  generic 
value. 

The  subfamilies  mentioned  in  the  key  that  do  not  come  within 
our  limits  are  placed  in  square  brackets.  The  Leptopix^  are 
mainly  Soutli  American,  the  remainder  occurring  mostly  in 
Australia;  the  Mickocerin.^  are  purely  African;  while'  the 
Braciiv'cerin'.^  are  predominatingly  African,  though  well  repre- 
sented in  the  Mediterranean  subreofion.

Subfamily  I.  BRACHYDERINiE. 

The  genera  o£  this  subfamily  are  very  poorly  represented  in 
the  Indian  subregion,  except  the  Tanymecides,  which  are  here 
more  numerous  than  in  any  other  part  of  the  world.  The 
character  that  distinguishes  this  group,  namely,  the  short  fringe 
of  curved  hairs  on  the  front  edge  ot  the  prothorax  below  the 
eye  (fig.  1,  d,  v),  is  always  conspicuous  in  good  specimens,  and 
the  hairs  are  very  rarely  lost  even  in  abraded  examples.  Another 
important  characteristic  is  the  structure  of  the  apical  portion  of 
the  hind  tibia.  This  is  obliquely  excised  on  its  inner  face  for 
the  reception  of  the  tarsus,  the  excision  being  known  as  the 
corbel,  and  being,  with  few  exceptions,  quite  devoid  of  scaling. 
When  the  outer  side  of  the  corbel  is  bounded  by  a  single  ridge 
fringed  with  bristles,  it  is  said  to  be  open  or  simple  ;  but  often 
there  may  be  observed  within  this  ridge  a  narrow  oblique  plate, 
the  inner  edge  of  which  forms  a  second  ridge,  also  fringed  with 
bristles,  and  in  such  a  case  the  corbel  is  described  as  enclosed.

Abraded  specimens  are  very  hke  B.  herthus,  Hbst.,  but  the 
latter  species  is  sHghtly  narrower  and  the  greatest  depth  of  the 
elytra  is  at  the  middle,  the  posterior  declivity  being  at  first  much 
more  gradual  and  becoming  more  abrupt  and  slightly  sinuate 
near  the  apex ;  the  central  furrow  on  the  forehead  narrows 
posteriorly  and  disappears  behind  the  eyes.  In  B.  oniscus  the 
greatest  depth  of  the  elytra  is  behind  the  middle  and  the  posterior 
declivity  is  eqvially  steep  throughout ;  the  central  furrow  is

Difiers  from  the  typical  form  only  in  the  structure  of  the 
prothorax,  which  is  much  less  rugose  in  appearance  owing  to  the 
granules  being  all  of  approximately  equal  size  and  without  the 
larger  tubercles  ;  the  sides  of  the  thorax  are  also  less  angulate 
and  therefore  it  appears  less  transverse  in  shape.  As  these 
characters  grade  into  those  of  B.  ina'qunUs  I  agree  with  Jekel  (7.  c.) 
in  regardiTig  the  present  form  as  merely  a  variety ;  it  is  probably

following  are  the  only  characters  by  which  I  am  able  to  dis- 
criminate it : — The  scape  when  folded  back  in  a  position  of  rest 
exceeds  the  posterior  margin  of  the  eye ;  the  second  joint  of  the 
funicle  is  always  a  little  longer  than  the  first ;  the  side-pieces  of 
the  meso-  and  meta-sternum  are  soldered  together  and  without 
definite  sutures,  except  that  sometimes  the  episternal  suture  of 
the  metasternum  is  visible  in  its  anterior  half. 

The  head  is  never  so  deeply  furrowed  as  in  most  species  o£ 
Blosyrtis,  the  legs  are  more  slender,  and  the  external  edge  of  the 
hind  corbels  is  never  inclined  inwards. 

Range.  N.E.  India  and  Burma.

Hah.  Bengal  (Mus.  Hope)." 

The  type  should  be  in  the  Oxford  Museum,  but  has  not  yet 
been  traced.  There  is  no  satisfactory  evidence  that  the  genus 
Stropliosonms  occurs  in  India,  and  I  have  therefore  tentative]}' 
assigned  this  species  to  Blositrodes.  The  carina  on  the  forehead 
distinguislies  it  from  all  the  known  members  of  the  genus,  but  in 
all  other  res[)ects  it  appears  to  be  extremely  like  B.  quaclrinodosus, 
Jek. 

Group  II.  NAUPACTIDES. 

Only  a  single  Indian  genus,  Cratopus,  Scbh.,  falls  within  this 
group.  Lacordaire  placed  it  among  his  Cyphides,  but  seeing  that 
the  corbels  ot  the  hind  tibias  are  not  enclosed,  it  appears  to  be 
more  satisfactorily  ])laced  in  the  Naupactides.  The  species  of 
this  group  are  mainly  American,  but  a  few  genera  occur  also  in 
Europe  and  Africa.

Type,  Cratopus  trianr/ularis,  Gyl.  (Mauritius). 

Head  exserted,  the  eyes  sublateral  and  longitudinal.  Itostrum 
continuous  with  and  shorter  than  the  head,  moderately  stout, 
almost  parallel-sided,  the  dorsal  edges  rounded,  the  apical  margin 
shallowly  sinuate ;  the  scrobes  broad  and  deep,  strongly  curved 
downwards  or  passing  obliquely  below  the  eyes,  lateral,  but  the 
lower  edge  often  visible  from  above ;  mandibles  with  a  distinct 
scar,  the  mentum  usually  supported  on  a  very  short  peduncle  and 
concealing  the  maxillse  (Indian  species),  but  occasionally  the 
peduncle  is  longer  and  the  maxillse  are  more  or  less  fully  exposed. 
Antenna'  slender  ;  the  scape  gradually  clavate,  reaching  or  exceed- 
ing the  posterior  margin  of  the  eye;  the  funicle  with  joints  3-7 
comparatively  short,  the  articulations  of  the  club  well  marked. 
Prothorax  transverse,  strongly  narrowed  in  front,  truncate  at  base 
and  apex,  the  apical  margin  slightly  oblique  at  the  sides,  without 
lobes  or  vibrissse.  ScuteUum  distinct,  variable.  Elytra  of  variable 
form,  not  very  broad  at  the  shoulders,  \\'hich  are  rounded  or 
sloping,  the  base  truncate  or  jointly  sinuate,  with  10  or  12  striae ;

margin  of  the  prosternum  ;  mesosternum  with  the  epimeron  only 
slightly  smaller  than  the  episternum  and  separating  it  from  the

Only  one  or  two  species  of  this  typically  insular  genus  have 
been  found  in  Africa.  Six  species  have  been  recoi'ded  by  Sclion- 
herr  from  India,  but  as  no  specimens  with  authentic  data  have 
since  been  received  from  that  country,  and  as  three  of  the  species 
are  known  to  occur  in  Mauritius  or  neif^hbouring  islands,  it  seems 
highly  probable  that  the  locality  given  lay  ychcinherr  for  all  these 
species  is  erroneous.

Type  5  in  the  British  Museum. 

Only  two  specimens  have  been  seen,  and  these  were  taken  as 
long  ago  as  1854.  Apart  from  the  characters  given  in  the  key, 
tliis  species  may  be  separated  from  C.  adspersiis,  Wtrh.,  by  its 
much  less  transverse  prothorax,  the  apically  produced  elytra, 
the  sloping  shoulders,  and  the  longer  last  ventral  segment,  which 
is  pointed  and  almost  equilateral,  whereas  in  the  other  two  species 
it  is  obtusely  rounded  and  the  sides  are  much  shorter  than  the 
base. 

Group  III.  ONEOREHINIDES. 

This  group  comprises  Lacordaire's  two  tribes,  Cneorrhinides 
and  Baryxotides,  between  which,  as  he  himself  admitted,  there 
is  no  real  dividing  line.  In  India  it  is  represented  merely  by  two 
species  of  a  purely  Palaearctic  genus,  Catapionus,  which  just 
encroaches  within  our  geographical  limits.

This  is  the  only  grou])  of  the  BRACiiYDEEiNiE  that  is  well 
represented  in  the  Indian  fauna,  and  more  genera  and  species 
are  known  from  this  subregiou  than  from  any  equal  area  in 
other  parts  of  the  world.  Moreover,  their  numbers  are  likely  to 
be  much  increased  when  the  beetles  of  the  Himalayas  have  been 
properly  collected,  for  numerous  localised  species  of  the  wingless 
section,  such  as  Le]itomias  and  its  allies,  :ire  certain  to  be  found 
there. 

With  one  or  two  exceptions,  the  early  stages  are  quite  un- 
known, and  but  little  has  been  recorded  as  to  the  habits  of  the 
adults  of  the  Indian  species,  apart  from  a  few  Asti/cus  and 
Tam/mecus  which  are  injurious  to  cultivated  plants.

corresponding  indentation  on  the  lower  surface  of  the  elytra,  which  serves  to 
accommodate  the  base  of  the  wing,  and  its  presence  may  be  taken  as  a  fairly

Genus  SCEPTICUS. 
Scepticiis,  Roeloffs,  Ann.  Soc.  Ent.  Belgique,  1873,  p.  158. 

Type,  Scepticus  insularis,  EoelofFs  (Japan), 

Head  with  the  eyes  quite  lateral,  almost  circular  and  prominent, 
forehead  as  broad  as  the  base  of  the  rostrum.  Rostrum  deflected, 
longer  than  the  bead  and  continuous  with  it,  very  slightly  emargi- 
nate  at  the  apex  ;  the  scrobes  broad  and  deep,  scarcely  dilated  and 
curving  downwards  close  beneath  the  eye ;  mandibles  rather  pro- 
minent, the  scar  projecting.  Antennoi  with  the  scape  cylindrical, 
clavate  and  reaching  the  middle  of  the  eye ;  the  funicle  with  the 
two  basal  joints  more  elongate,  3-6  subequal  and  bead-like,  7 
larger  and  subconical,  the  club  ovate  and  4-jcinted,  the  first  joint 
much  longer  than  the  second.  Protliorax  truncate  at  the  base 
and  apex,  the  latter  narrower,  the  sides  rounded,  the  gular  margin 
distinct!}^  sinuate,  the  coxae  slightly  nearer  the  front  margin  of 
the  prosternum.  Scutellum  very  small.  Elytra  raarginate  at  the 
Imse,  the  margin  scarcely  raised,  the  shoulders  sloping  and  with- 
out a  humeral  prominence,  tlie  lateral  margin  scarcely  or  very 
shallowly  sinuate.  Sternum  with  the  epimera  of  the  mesosternum 
much  smaller  than  their  episterna,  and  scarcely  se|>arating  them 
from  the  base  of  the  elytra  ;  the  metasternum  slightly  shorter 
than  the  median  coxae,  the  episterna  fused  v^ith  it  so  that  no 
suture  is  visible,  the  episterna  themselves  mostly  hidden  beneath 
the  elytra,  but  with  the  dilated  anterior  piece  exposed  and  distinct, 
the  hind  coxae  reaching  the  elytra.  Venter  with  the  iutercoxal 
piece  truncate  and  about  as  broad  as  the  coxae,  segment  !2  longer 
than  3  +  4  and  separated  from  1  by  a  curved  suture  of  even  depth. 
Legs  moderate,  the  femora  slightly  clavate,  the  front  pair  not 
thickened  ;  the  front  tibia)  only  slightly  curved  and  not  denti- 
culate, the  hind  pair  straight,  with  its  corbels  large,  triangularly 
dilated,  narrowly  enclosed,  slightly  ascending  the  dorsal  edge  and

Roeloffs  placed  this  genus  in  the  Brachyderides,  but  his  type 
species,  from  Japan,  has  well  developed  postocular  vibrissse,  and 
should  undoubtedly  be  referred  to  the  Tanymecides,  in  the 
vicinity  of  Tlujlacites,  to  which  it  is  closely  allied.  The  latter 
genus  differs  iu  having  the  base  of  the  elytron  gradually  sloping 
to  its  edge,  instead  of  being  sharply  niarginate  ;  the  nietasternum 
is  evidently  longer  than  the  median  coxte  ;  the  corbels  of  the 
posterior  tibise  are  covered  with  scaling  internally,  and  the  third 
joint  of  the  posterior  tarsi  is  scarcely  broader  than  the  second. 
The  two  species  of  Thi/lacitfs  described  by  Faust  from  Kashmir 
should,  I  consider,  be  referred  to  the  present  genus,  which  has 
hitherto  been  regarded  as  peculiar  to  Japan.

Head  with  the  eyes  lateral  and  variable  in  shape.  Rostrum 
varying  in  length,  the  base  not  or  only  slightly  broader  tlian  the 
forehead,  the  sides  straight,  the  apical  emargination  variable ;  the 
scrobes  varying  in  structure ;  the  mandibles  with  a  distinct  de- 
pressed scar  ;  the  nientura  of  variable  shape,  the  submentum  not 
pedunculate.  Antennce  inserted  at  the  middle  or  before  the  middle 
of  the  rostrum,  the  scape  gradually  thickened  or  rather  abruptly 
clavate,  reaching  at  least  the  middle  of  the  eye,  but  usually 
exceeding  the  hind  margin  ;  the  futiicle  with  the  two  basal  joints 
more  elongate,  3-7  subequal,  varyiug  from  slightly  transverse  to 
longer  than  broad,  the  club  elongate  acuminate  and  4-jointed. 
Prothorax  truncate  or  slightly  rounded  at  the  base,  truncate 
at  the  apex  and  with  distinct  vibrissse,  the  gular  margin  usually 
with  a  shallow  sinuation.  Scutellum  distinct,  triangular.  Elytra 
variable  in  shape,  truncate  or  sinuate  at  the  base,  with  a  humeral 
callus,  the  shoulders  generally  well  developed,  but  sometimes  very 
oblique  and  only  slightly  broader  than  the  prothorax,  the  lateral 
mai'gin  very  shallowly  sinuate  above  the  hind  coxae  and  with  a 
small  emargination  near  the  base.  Sternum  with  the  front  coxse 
much  nearer  the  anterior  margin  of  the  prosternum ;  the  meso- 
sternum  with  the  epimera  large ;  the  metasternum  as  long  as  or 
longer  than  the  median  coxa?,  the  episterna  broad  and  distinct, 
the  hind  coxap  not  reaching  the  elytra.  Venter  with  the  inter- 
coxal  process  rounded  or  angulate  and  much  narrower  than  the 
hind  coxae,  segment  2  as  long  as  or  longer  than  3  +  4  (except  in 
T.  Jtonbiramis,  Msh!.,  and  a  few  African  species)  and  separated 
from  1  by  a  curved  incision,  which  is  usually  fainter  in  the  middle. 
Legs  elongate  and  slender,  the  femora  moderately  clavate  ;  the 
tibiae  almost  straight  externally,  often  denticulate  internally,  the 
two  anterior  pairs  with  the  internal  apical  angle  produced,  the  two 
posterior  pairs  with  their  corbels  open  and  narrowly  ascending 
the  dorsal  edge  for  some  distance  and  fringed  with  short  setae ; 
the  tarsi  generally  slender,  the  claws  long  and  free.

Faust  has  always  kept  Esamus  and  Tanymeeus  as  distinct 
genera,  giving  as  diagnostic  characters  cez'tain  differences  in  the 
dilatation  and  direction  of  the  scrobes,  in  the  relative  lengths  of 
tlu*  ventral  segments,  in  the  emargination  of  the  apex  of  the 
rostrum  and  the  shape  of  the  elytra ;  and  he  confines  the  name 


TANYMECUS.  69 

Tanijmems  to  the  species  having  the  facies  of  T.  indicas,  Vat. 
JBut  after  examining  a  large  number  of  species  from  all  parts  of 
their  range,  I  iind  that  every  one  of  these  characters  is  liable  to 
such  serious  exceptions  that  it  is  impossible  to  accept  them  as  of 
generic  value. 

India  would  appear  to  be  the  head-quarters  of  the  genus,  as  at 
present  known,  and  no  fewer  than  43  species  are  here  recorded 
from  within  our  limits.  These  weevils  in  the  adult  stage  frequent 
shrubs  and  low-growing  plants,  and  their  colouring  is  for  the 
most  part  coniined  to  greys  and  browns,  though  in  a  few  species, 
such  as  T.  hei'cales,  T.  verlorenii,  T.  clievrolati,  and  T.  princeps,  the 
scaling  is  of  a  uniform  metallic  green  coloiu".  In  the  very  few 
cases  in  which  the  full  life-history  is  known  the  larvae  are 
subterranean  root  feeders. 

The  sexes  diifer  but  little  in  general  form,  though  well-marked 
distinctions  are  usually  to  be  found  on  the  ventral  surface  of  the 
female.  In  most  species  the  last  segment  of  the  venter,  which 
is  always  more  pointed  in  the  female,  bears  on  each  side  a  narrow- 
bare  raised  line  on  the  basal  half,  while  in  many  cases  its  apex  is 
more  or  less  strongly  compressed,  sometimes  forming  quite  a  sharp 
ridge ;  in  T.  andreivesi  the  third  segment  is  deeply  impressed  and 
partly  withdrawn  beneath  the  second,  while  in  T.  pertusiventris 
the  same  segment  has  a  deep  round  impression  on  each  side.  In 
T.  versicolor  an  unusual  sexual  difference  may  be  observed,  namely, 
the  presence  of  a  long  curved  spur  at  the  apex  of  the  middle  tibiae 
in  the  female  only. 

Tawjmecus  rudis,  which  was  described  by  Gylleuhal  as  coming 
from  India,  proves  to  be  an  African  species.

Very  similar  in  general  aspect  to  T.  chevrolati,  Fhs.  (with  which 
it  was  confused  b_y  Faust),  but  differing  from  it  in  the  following 
particulars  : — the  scape  is  longer  and  when  at  rest  reaches  the 
posterior  margin  of  the  eye :  the  prothorax  entirely  lacks  the 
central  carina  and  the  bare  discal  spot ;  the  elytra  are  more 
divergent  at  the  apex  ;  the  c?  organ  is  more  robust  and  the  lateral 
outline  of  its  dorsal  carina  forms  a  continuous  curve,  and  is  not 
deeply  sinuate  as  in  T.  chevrolati.

Owing  apparently  to  a  mistake  on  the  part  of  Westermanu,. 
Schouherr  concluded  that  his  T.  cdbomargiaatns  was  identical 
with  T.  circamdatm,  Wied.,  and  this  has  been  followed  by  sub- 
sequent  authors.  An  examination  of  Wiedemann's  type,  which 
agrees  well  with  his  description,  shows  this  to  be  an  error.  The 
species  is  variable  both  in  size  and  colour,  but  the  following 
variety  alone  seems  to  be  worthy  of  recognition. 

T.  circumdatiis  var.  rusticus,  Gyl. 

This  form  is  on  the  average  a  good  deal  smaller  and  the  elytra 
lack  the  alternate  darker  and  paler  stripes,  the  scaling  being 
denser  on  the  intervals  1-3  and  thinner  on  4-6.

T.  leucocephcdus,  Chev.,  and  T.  suhanreus,  Desb  ,  are  both 
synonyms  of  this  variation. 

The  name  2\  falsvs  was  given  by  Chevrolat  to  this  species 
because  he  thought  that  T.  rusticus,  Gyl.,  was  the  same  as  Hypomeces 
rusticus,  r.  His  typical  specimen  has  more  or  less  green  scaling 
on  the  upper  surface,  and  this  form  appears  to  be  prevalent  in 
the  Punjab.

Tliis  species  is  extremely  close  to  T.  princeps,  Fst,,  and  it  is 
doubtful  whether  it  can  be  regarded  as  more  than  a  slight  local 
variation.  The  distinctive  characters  assigned  to  it  by  Faust  are 
as  follows  : — "  Shoi'ter,  beneath  more  densely  and  above  more 
sparsely  clothed  with  opctque  green  scales;  forehead  and  rostrum 
broader,  the  latter  very  short;  antennae  red-brown;  ])rotliorax 
half  as  long  again  as  its  width  ;  elytra  shorter,  the  punctures  in

This  insect  has  proved  a  serious  agricultural  pest  in  certain 
districts.  The  damage  hitherto  recorded  has  been  done  by  the 
adult  weevils,  which  live  on  the  ground,  hiding  among  the  loose 
clods  in  the  fields  and  nibbling  off  the  young  germinating  plants 
during  the  first  four  or  five  days  of  their  growth  in  the  spring. 
The  crops  that  are  more  particularly  attacked  are  wheat,  peas  and 
gram,  and  less  frequently  barley.  In  some  cases  crops  have  had 
to  be  planted  three  times  over  on  account  of  the  attacks  of  these 
weevils.  It  is  stated  that  they  are  attracted  by  the  smell  of 
haitha  and  hel  fruits,  which  are  sometimes  used  by  cultivators 
for  trapping  them  (Ind.  Mus.  Notes,  iii,  1893,  p.  12  ;  iv,  1899, 
pp.  123  and  188).

Very  similar  to  T.  indicus,  Pst.,  and  differing  only  in  the 
following  characters  : — The  rostrum  is  much  shorter  and  broader, 
being  broader  than  long;  the  forehead  is  broader  and  more 
convex,  the  narrowest  space  between  the  eyes  being  as  broad  as 
the  base  of  the  rostrum,  whereas  in  T.  indicus  the  latter  part  is 
slightly  broader  ;  the  scape  of  the  antennae  is  leather  more  slender 
and  more  abruptly  clavate ;  the  prothorax  is  broadest  before  the

a  5  .  It  is  extremely  close  to  T.  indims,  Fst.,  from  which  it  differs 
only  in  the  followiug  points  :— The  prothorax  has  a  broad  shallow 
constriction  near  the  ajiex  and  its  central  carina  is  complete  and 
rather  more  pronounced  ;  the  elytra  are  rather  broader,  being 
parallel-sided  from  the  shoulders  to  beyond  the  middle  ;  the  anal 
segment  has  no  median  impression. 

Whether  these  differences  are  really  specific  or  merely  indi- 
vidiial  cannot  be  decided  without  more  material  and  an  examination 
of  the  (5  genitalia.

This  is  another  very  close  ally  of  T.  indicus,  Fst.,  from  which  it 
differs  only  in  the  following  points  : — The  eyes  are  slightly  more 
prominent  and  less  elongate,  being  evidently  shorter  that  the 
rostrum  ;  the  forehead  is  more  flattened ;  the  scrobe  is  narrower, 
more  angulate  and  not  clothed  with  scaling  ;  the  scales  are  broader 
and  coarser,  and  the  setae  are  therefore  more  evident,  especially 
on  the  under  surface ;  the  anal  segment  of  the  $  has  no  median 
impression ;  the  (S  organ  is  sharply  pointed  at  the  apex,  whereas 
it  is  broadly  rounded  in  indicus.

of  the  prosternum  and  with  a  large  bifid  tubercular  prominence 
behind  the  coxae  ;  the  mesosternum  with  the  epimera  and  episterna 
of  almost  equal  size ;  the  metasternum  much  longer  than  the 
median  coxa?,  the  episterna  broad  and  distinct,  the  hind  coxsb  not 
reaching  the  elytra.  Venter  with  the  intercoxal  process  broadly 
rounded,  segment  2  longer  than  3  -|-  4,  and  divided  from  1  by  a 
sinuate  incision  which  is  shallower  in  the  middle.  Legs  with  the 
femora  clavate ;  the  tibite  almost  straight,  except  the  front  pair 
which  are  slightly  bent  in\^ards  near  the  apex  and  have  an  internal 
apical  process,  the  hind  pair  with  the  corbels  open  and  ascending 
the  dorsal  edge  for  some  distance  ;  the  tarsi  bi-oad,  joint  4  elongate, 
the  claws  strongly  connate ;  the  trochanters  with  an  isolated  long 
projecting  bristle. 

Eaiir/f."  Eastern  India,  Burma,  China  and  the  Malay  Archipelago

The  only  constant  difference  in  the  sexes  is  to  be  found  in  the 
last  ventral  segment,  which  bears  two  short  longitudinal  sulci  at 
the  base  in  the  $  ,  that  of  the  d  being  simple.  In  B.  squamosus, 
Y.,  and  unicolor,  Weber,  the  sexes  are  of  nearly  the  same  shape, 
but  the  cJ  is  clothed  with  long  fine  erect  pubescence,  which  is 
lacking  in  the  5  .  But  in  H.  infatns,  Chev.,  from  Elores,  both 
sexes  are  pubescent,  while  the  elytra  of  the  2  are  much  broader 
than  those  of  the  c5~ .

It  is  with  some  doubt  that,  in  accordance  with  the  opinion  of 


118  CUECULlOyiD,!]. 

Faust,  this  species  is  here  separated  from  squamosus,  F.,  the  only 
discriminative  characters  being  tlie  absence  of  the  projecting  tooth 
at  the  anterior  angles  of  the  protboi'ax  and  the  greater  curvature 
of  the  sides  of  the  prothorax,  especially  in  the  J  ;  but  in  some 
cases  even  these  appear  ambiguous. 

Eange  similar  to  that  of  squamosus,  bat  occurring  also  in  Borneo, 
Flores  and  Timor. 

T9/2ie.  I  am  not  aware  that  Weber's  types  have  yet  been  traced 
with  certainty ;  the  specimens  described  by  Fabricius  from  Dal- 
dorff's  collection  are  in  the  Copenhagen  University  Museum,  and 
it  is  not  unlikely  that  they  are  the  actual  insects  described  by 
Weber. 

This  species  exhibits  the  same  range  of  colour  variations  as 
squamosus.  The  d  genitalia  of  both  forms  exhibit  a  certain 
amount  of  variation  in  length,  curvature,  etc.,  but  no  character 
has  been  found  b}^  which  the  two  forms  can  be  discriminated.

throughout  India,  Ceylon,  Arabia  and  Africa. 

In  spite  of  its  somewhat  heterogeneous  appearance,  I  must 
agree  with  Faust  that  this  genus  cannot  be  satisfactorily  sub- 
divided.

Genus  DYSCHERES. 
Dyscheres,  Pascoe,  Notes  Leyd.  Mus.  v,  1883,  p.  83. 
Type,  D.  agrestis,  Pasc.  (Malay  Archipelago). 

From  Dereodus,  Schh.,  this  genus  can  only  be  distinguished  bv 
the  fact  that  the  corbels  of  the  hind  tibiae  are  not  clothed 
with  scales,  nor  do  they  ascend  the  dorsal  edge  of  the  tibia,  and 
the  trochanters  are  furnished  with  a  solitary  long  projecting 
bristle.  The  species  at  present  known  also  differ  in  having  the 
posterior  angles  of  tlie  prothorax  acutely  prominent. 

Range.  Burma,  and  the  Malay  Peninsula  and  Archipelago. 

In  addition  to  the  type  and  the  single  Burmese  species  only 
one  other  species  is  known,  namely,  D,  curtus,  Pasc,  from  Timor.

In  addition  to  the  type  I  have  seen  only  a  single  specimen,

Dr.  ileller  has  already  suggested  (Stett.  Ent.  Zeit,  1908,  p.  125) 
the    possibility   that   Faust   had    gone    too    far  in  his  attempts 


130  CUECDLIOKID.i:. 

to  split  i;p  the  genus  Astycns ;  for  the  latter  has  recognised  as 
valid  genera  every  one  ot"  the  names  which  are  here  treated  as 
synonvms.  The  examination  of  a  considerable  amount  of  addi- 
tional material  (for  there  are  here  enumerated  16  species  which 
were  unknown  to  Faust)  shows  that  the  characters  upon  which  he 
relied  for  liis  genera  are  all  liable  to  such  serious  exceptions  that 
they  must  be  treated  merely  as  specific,  and  not  generic  distinc- 
tions. The  principal  characters  that  lie  utilised  were  the  curvature 
of  the  scrobe,  the  tibial  furrows,  the  relative  length  of  the  mela- 
sternum.,  tlie  proportions  of  the  two  basal  joints  of  the  fuuicle, 
and  the  sliape  of  the  elytra. 

Schouherr  actually  cited  as  the  ty]ie  of  Astijcns,  Curculio  adultns, 
Oliv.,  a  species  which  he  had  only  doubtfully  identified  ;  but  the 
insect  he  had  before  him  is  imquestionably  conspecific  with

Schonherr  (I.  c.)  suggested  that  Curcidio  achdtus,  Oliv.,  might 
be  the  grey  form  of  this  species  ;  Avhile  Paust  has  assigned  that 
name  to  specimens  which  he  separates  specifically  from  A.  chrgso- 
cJilorus.  Through  the  kindness  of  Dr.  Heller  I  have  been  able  to 
examine  two  of  these  specimens,  and  I  cannot  regard  them  as 
specifically  separable  from  Wiedemann's  species.  Unfortunately 
M.  P.  Lesne  informs  me  that  he  cannot  recognise  Olivier's  type 
with  certainty  in  the  Paris  Museum  Collection,  from  which  it  was 
described.  But  seeing  that  Olivier  definitely  gives  Surinam  as 
the  locality  of  his  insect,  there  may  yet  be  found  a  South  Ameri- 
can species  which  can  be  referred  to  it.  If  the  name  is  to  be  used 
for  an  Indian  insect,  Olivier's  crude  figure  agrees  best  with  the 
species  here  described  as  A.  neglectns,  sp.  nov.

Colour  black,  with  dense  metallic  green  scaling,  each  elytron 
having  two  broad  golden  yellow  stripes,  one  on  interval  2  and 
half  of  3,  the  other  partly  on  intervals  7  and  8  ;  these  stripes 
unite  broadly  near  the  apex  and  almost  meet  at  the  base. 

The  only  constant  external  structural  characters  by  which  this 
species  can  be  distinguished  from  A.  chrysochlurvs,  "\Vied.,  are 
that  the  rostrum  is  slightly  convex  dorsally,  the  lateral  margin 
being  less  sharply  defined  and  the  sides  less  steep  ;  the  second 
joint  of  the  funicle  is  distinctly  longer  than  the  first ;  the  elytra 
are  proportionately  much  narro^^•er,  the  basal  margin  being  more

deeply  sinuate  and  more  strongly  reflexed.  The  genitalia  of  tlie 
J  ,  however,  afford  a  satisfactory  specific  distinction.  In  cliryso- 
chlorus  the  male  organ  lias  a  distinct  median  dorsal  carina;  from 
a  lateral  aspect  the  outline  forms  a  regular  curve  both  above  and 
below,  being  deepest  at  about  one-fourth  from  the  apex.  In 
Jlavovittatus  there  is  no  dorsal  carina ;  the  dorsal  outline  is  sinuate 
at  about  one-fourth  from  the  apex,  the  ventral  outline  being 
sinuate  quite  close  to  the  aj^ex ;  the  depth  is  uniform  from  near 
the  base  to  beyond  the  middle,  diminishing  thence  to  the  apex.

QQ.  Astycus  sylhetensis,  sp.  nov. 

Colour  black,  with  rather  thin  metallic  green  scaling  ( cJ  )  or 
with  grey  scaling,  sometimes  having  a  metallic  reflexion  (  $  ),  the 
granules  on  the  prothorax  and  elytra  black  and  bare. 

Closely  allied  to  A.  dorice,  Fst.,  but  the  upper  part  of  the  fore- 
head is  granulate;  the  prothorax  has  the  sides  more  strongly 
rounded,  the  granules  being  of  the  same  size  but  more  closely 
placed,  and  there  is  no  trace  of  a  central  furrow;  the  elytra  are 
evidently  shorter  in  proportion  to  their  breadth  and  more  broadly 
rounded  posteriorly  than  in  dori'i' ;  the  femora  are  black  and 
much  more  densely  clothed  with  scaling ;  the  green  scaling  is  less 
metallic  and  lacks  the  blue  tinge  of  do7-ice.  The  anal  segment  of 
the  5  is  only  slightly  compressed  at  the  apex,  being  similar  to

In  addition  to  its  great  variability  in  the  matter  of  size,  this 
species  varies  in  the  shape  of  the  prothorax  of  the  cT .  In  the 
smallest  specimens  the  prothorax  entirely  resembles  that  of  the  $  , 
but  in  the  larger  examples  its  sides  are  much  more  rounded,  and 
it  becomes  almost  globular  in  shape,  thus  giving  the  insect  a  very 
■different  appearance.

A.  oculatus  var.  levicollis,  nov. 

This  local  form  differs  from  the  type  in  the  structure  of  the 
protliorax.  In  the  J  this  segment  entirely  lacks  the  dorsal 
granules,  being  smooth  and  shiny,  with  scattered  sliallow  punctures. 
This  character  is  not  so  well  marked  in  the  two  $  specimens,  as 
the  granules  are  present  in  the  middle  of  the  basal  half,  but  tlie 
anterior  and  lateral  areas  are  as  smooth  as  in  the  i^  .  The  d 
genitah'a  quite  resemble  those  of  the  typical  form.

Colour  black,  with  blackish  scaling  and  with  the  following  green 
or  colden-green  markings :  a  broad  lateral  stripe  on  the  head  and 
prothorax,  a  narrow  central  line  on  the  latter,  which  continues 
right  along  the  suture  of  the  elytra  to  its  apex,  on  each  elytron  a 
broad  stripe  running  from  the  base  of  intervals  3-5  (or  only  4

equally  broad  lateral  stripe,  which,  however,  does  not  reach  the

Very  closely  allied  structurally  to  A.  griseus,  Desbr.,  but 
differing  as  follows :  the  anterior  part  of  the  forehead  and  the 
base  of  the  rostrum  are  more  convex,  much  more  shiny,  and  more 
finely  punctate  ;  the  bead  has  no  central  furrow,  but  there  is 
usually  a  shallow  fovea  on  the  vertex  and  another  on  the  antei'ior 
part  of  the  forehead,  which  is  sometimes  continued  just  on  to  the 
base  of  the  rostrum  ;  the  rostrutn  itself  lacks  the  sharply  defined 
central  furrow  of  A.  griseus,  there  being  merely  a  shallo\^"  im- 
pression about  the  middle.  Pi'othorax  with  the  setas  on  the  disk 
short  and  fine,  tbose  at  the  sides  mucli  longer ;  whereas  in  A.

Despite  certain  discrepancies,  I  have  not  much  hesitation  in 
attributing  the  description  of  Arlunes  destructor,  Nietn.  (I  do  not

Concerning  this  msect  Mr.  James  Eose,  as  quoted  by  Nietner 
{op.  cit.  p.  121),  says  :  "The  ravages  which  these  insects  commit 
[on  coffee  plants]  are  really  terrible  ....  Five  or  six  acres  have 
been  completely  covered,  and  they  have  destroyed  nearly  all  the 
leaves.  This  year  they  have  appeared  in  great  number,  where 
they  have  covered  at  least  40  acres."  Mr.  E.  E.  Green  informs 
me  that  this  species  also  defoliates  young  tea  plants.

LEPIDOSPYIUS,  153 

Genus  LEPIDOSPYRIS,  nov. 
Type,  Astijcophohus  cretaceus,  Fst, 

Head  with  the  eyes  quite  lateral,  the  forehead  almost  as  wide 
as  the  base  of  the  rostrum.  Mostrum  longer  thau  the  head,  with 
a  median  impression  and  a  dorsal  carina  on  each  side,  the  apex 
with  a  fairly  deep  angular  emarginatiou ;  the  scrobe  curving 
downwards  at  some  distance  in  front  of  the  eye  and  but  little 
dilated  behind ;  mandibles  with  a  prominent  scar,  the  mentum 
with  two  or  four  setje  close  to  the  front  edge.  Antennce,  prothorax 
and  elijtra  as  in  Asti/cns,  except  as  regards  the  scales,  each  of 
which  has  a  boss-like  elevation  in  the  middle.  iSteraum  with  the 
front  coxae  rather  widely  separated  and  very  close  to  the  front 
margin  of  the  prosternum  ;  the  mesepimeron  much  smaller  than 
its  episternum,  its  outer  margin  distinctly  sinuate;  the  meta- 
sternum  slightly  longer  than  the  median  coxjb.  Venter  and  lef/s 
as  in  Astyciis,  except  that  the  tibiae  are  never  sulcate,  and  the 
corbels  of  the  hind  pair  are  more  or  less  clothed  with  scales 
internally. 

RaiKje.  India. 

The  members  of  this  genus  are  very  similar  to  the  small  grey 
species  of  Astycus  in  general  ap])earance,  but  may  be  distinguished 
by  the  scaly  corbels  of  the  hind  tibia;,  and  by  the  embossed  and 
overlapping  scales  of  the  upper  surface.

This  genus  forms  one  of  the  links  which  unite  the  flying 
Tantmecides  with  the  group  in  which  functional  wings  are 
absent.  Jb'or  many  of  the  species  possess  a  humeral  fold  or  false 
shoulder,  giving  them  a  close  resemblance  to  the  smaller  species 


160  cuRCULio>'ii^.i:. 

of  Astyciis,  with  which  indeed  Schunherr  associated  them.  Several' 
of  them  also  exhibit  traces  of  the  small  basal  lateral  notch  on  the 
elytra,  which  is  characteristic  of  the  genera  having  functional 
wings;  while  the  fact  that  the  episternum  is  in  no  way  fused 
with  the  metasternum  suggests  that  the  power  of  flight  has 
been  lost  somewhat  recently.  But  these  species  can  at  once  be 
distinguished  from  Astycus  by  their  non-functional  hind  wings, 
by  the  comparatively  small  size  of  the  epimera  of  the  meso- 
sternum  and  the  relatively  shorter  metasternum. 

Throughout  most  of  the  genus  the  external  structure  is  very 
uniform,  and  an  examination  of  the  S  genitalia  has  been 
necessary  ;  but  in  many  cases  colour  appears  to  furnish  quite  a 
reliable  specific  character.

Pronounced  examples  of  this  variety  appear  very  different  from 
the  typical  form,  but  they  certainly  grade  into  one  another,  and 
in  the  case  of  the  oidy  d"  that  I  have  dissected  the  genitalia  are 
indistinguishable  from  those  of  typical  /S'.  prasinus. 

121.  Sympiezomias  praeteritus,  sp.  nov. 

Colour  black,  with  glittering  metallic  green  scaling,  the  inflexed 
sides  of  the  prothorax  and  elytra  and  the  base  of  the  prothorax 
yellowish ;  the  green  of  the  elytra  sometimes  partly  replaced  by 
pale  fawn  scaling  (?  immature). 

Extremely  close  to  S'.  prasinus.  Boh.,  from  which  it  differs  in 
the  following  characters  : — The  elytra  are  slightly  more  elongate 
and  the  basal  margin  more  raised  ;  the  humeral  fold  is  much  less 
developed,  beii]g  practically  absent  in  the  J ,  while  in  the  $  it 
does  not  project  beyond  the  lateral  outline  of  the  elytra  as  seen 
from  above  ;  the  scaling  is  also  characteristic,  the  scales  having 
flattened,  highly  polished  surfaces  which  produce  a  glittering 
effect  that  is  never  seen  in  S.  prasinus ;  the  dorsal  outline  of  the 
elytra  is  a  little  less  convex  near  the  base,  and  the  third  interval

is  not  higher  than  the  second  on  the  declivity,  as  it  is  in  >S'.  p>-a- 
sinus.  The  differences  in  the  male  organ  are  slight,  but  constant; 
in  lyrasinus  it  is  deeper  to\Aards  the  apex  than  in  the  middle, 
whereas  it  is  o£  even  depth  in  _2>rf<f^«riiws,  in  which  also  the  pro-

Head  with  deep  scattered  punctation,  the  rostral  furrow  some- 
times encroaching  on  the  forehead,  liostrum  plane  above  and 
with  a  broad  central  furrow,  the  dorsal  carinas  gradually  con- 
vergent behind.  ProiJiorax  a  little  broader  than  long,  the  sides 
slightly  rounded,  broadest  about  the  middle,  the  apical  margin 
obliquely  truncate  at  the  sides,  the  upper  surface  with  shallow 
contiuent  punctation  which  is  mor '  or  less  hidden  by  the  scaliug, 
and  often  with  a  faint  abbreviated  stria  in  the  middle.  Elytra 
with  the  basal  margin  distinctly  elevated,  the  humeral  fold  rather 
feeble,  especially  in  the  6 ,  the  dorsal  curvature  somewhat  flat, 
but  steeply  declivous  behind,  the  apices  scarcely  mucronate  in  the 
(S  aud  with  a  short  mucro  in  the  $  ,  strongly  punctato-striate 
but  with  the  punctures  partially  hidden  by  scaling,  the  dorsal 
intervals  a  little  narrower  than  the  striae  in  the  6  ,  broader  in 
the  §  ,  the  longitudinal  curvature  very  flat  and  becoming  abruptly 
steeper  on  the  declivity,  which  is  not  impressed  ;  the  setae  short, 
broad  and  curved,  and  mucli  more  numerous  in  the  lateral  stripe 
than  on  the  disk.

13<>.  Sympiezomias  anamalainus,  sp.  nov. 

Colour  black,  with  thin  grev  or  bluish-grey  scaling ;  the  pro- 
thorax  with  an  ochreous  yellow  lateral  stripe ;  the  elytra  Avith  a 
similar  stripe  on  intervals  6  and  7,  extending  inwards  at  the  base 
and  near  the  apex  as  far  as  interval  4,  aiul  with  some  ochreous 
scaling  along  the  margin. 

A'ery  closely  allied  to  S.  sidjjhuratus,  sp,  n.,  with  the  following 
differences  : — Head  finely  punctate,  the  forehead  with  a  central 
stria,  wliich  sometimes  extends  up  to  the  vertex;  the  rostrum 
shallowly  impressed  dorsally,  and  with  the  dorsal  carinas  parallel 
posteriorly  ;  the  prothorax  moi-e  coarsely  sculptured ;  the  elytra 
with  the  sides  more  rounded,  and  the  discal  setae  much  smaller, 
microscopic  ;  the  second  tarsal  joint  without  a  trace  of  true  scales. 
The  male  organ  is  not  deeper  towards  the  apex  than  in  the  middle, 
and  the  spatula  is  not  nearly  so  sharply  pointed.  This  organ  is 
very  similar  to  that  of  S.  acutipennis,  Boh.,  but  the  latter  is  more 
poiiited  and  more  curved  upwards  at  the  tip.  This  species  differs 
also  in  having  the  head  more  coarsely  punctate  and  without  a 
central  stria,  and  the  eyes  less  convex  ;  the  prothorax  is  more 
finely  sculptured ;  the  elytra  lack  the  stripe  of  dense  broad 
set^e  towards  the  sides,  and  there  is  a  strong  impression  on  the 
declivitv.

Head  with  the  eyes  lateral,  broadly  ovate  and  moderately  pro- 
uiinent,  the  forehead  as  broad  as  the  base  of  the  rostrum,    llostntm 
longer  than  the  liead  and  continuous  with  it,  with  a  very  small 
apical  emax'ginatiou,  without  distinct  cariniie  above  and  without 
a  lateral  impression  in  front  of   the  eye;    the  scrobes  generally 
deep   and  sublinear  throughout,  but   occasionally  shallower  and 
broader  behind  (L.  cmgusiatus,  L.  invidus) ;  the  mandibular  scar 
projecting.     Antennce  with  the  scape  cylindrical,  clavate,  slightly 
curved   and  of  variable  length  ;    the  funicle  with   joint  1  much 
longer    than    2     (except  in  L.  lonyulus,   Fst.,    and  L.   curvipes^ 
Mshl.),  3-6  subequal  and  bead-hke,  7  longer  and  subconical ;  the 
club  elongate,  sharply  acuminate,  4-jointed.     Prothonuv  truncate 
at  base  and  apex,  the  sides  rounded,  the  base  narrowly  marginate, 
the  coxae  very  near  the  gular  margin,  which  is  shallowly  sinuate. 
SciUellum  ver}'  small  or  invisible.     Elytra  marginate  at  the  base, 
the  edge  being  nearly  alwavs  elevated,  without  true  shoulders,  the 
lateral   margin   scarcely  sinuate.     Sternum  with   the   mesosternal 
epimera  much  smaller  than   their  e]nsterna  and  not  separating 
them  from  the  base  of  the  elytra ;  the  metasternum  generally  as 
long  as  the  median  coxte,  rarely  shorter  (L.  hipustalatus,  L.  stidtus), 
the  epi sterna  distinct,  but  scarcely  dilated  at  the  anterior  end, 
the  episternal  suture  complete,  the  hind  coxae  almost  touching  the 
elytra.      Venter  with  the  intercoxal  process  rounded  or  subangu- 
late,  segment  2  as  long  as  3  +  4  and  separated  from  1  by  a  curved 
suture  of  even  depth.     Ler/s  with  the  femora  clavate,  the  anterior 
pair  being  rather  thicker  ;  the  tibioe  without  a  distinct  apical  spine, 
the  front  pair  curved,  denticulate  along  the  inner  edge  in  both  sexes 
and  produced  internally  at  the  apex,  the  hind  ])air  almost  straight, 
minutely  serrate  internally  in  tlie  d  (except  L.  waltoni),  the  pos- 
terior corbels  triangular,  narrowly  enclosed  and  slightly  ascending 
the   dorsal  edge  ;    tarsi   with  joint  3  broadly  lobate,  the  claws 
connate  at  the  base. 

Range.  The  mountain  regions  of  Northern  India  and  Tibet. 
This  is  one  of  the   many  subdivisions   of  the  genus  Piazomias, 
Schonh.,  suggested  by  Faust,  and  there  are  two  characters  by  which 
the  latter  genus,  as  restricted  by  him,  may  be  distinguished  from 


LEPXOMIAS. 


Leptomias,  as  here  defined  :  (1)  the  metasternum  is  fused  with  its 
episterna,  so  that  the  suture  has  disappeared  except  close  to  the 
hind  coxfe  ;  (2)  the  corbels  of  the  hind  tibiae  are  entirely  open. 

The  distinctions  given  by  Eaust  for  his  genus  Heteromias  are 
that  the  scrobe  is  not  dilated  behind,  and  that  the  metasternum  is 
shorter  than  the  median  coxas.  But  these  characters  occur  inde- 
pendently in  various  species  which  he  himself  referred  to  Leptomias, 
and  the  genus  therefore  cannot  be  retained.  For  similar  reasons 
I  am  unable  to  recognise  the  genns  Parisomias,  Fst.  It  may  ba 
noted  that  the  generic  name  Heteromias  was  originally  used  without 
description  and  even  witliout  any  mention  that  it  was  considered 
to  be  a  new  genus  (Stettin.  Ent.  Zeit.  1888,  p.  285).

IGO.  Leptomias  curvipes,  sp.  nov. 

Colour  black,  the  elytra  with  irregular  patches  of  very  small 
sparse  grey  scales ;  the  pronotum  with  a  narrow  curved  stripe  on 
each  side  formed  of  similar  scales. 

Head  with  oidy  a  few  scattered  scales  ;  the  vertex  coriaceous, 
the  forehead  shallo\^'ly  punctate  and  wrinkled,  with  a  distinct 
central  furrow  which  becomes  rather  abruptly  broadei-  and  deeper 
in  front.  Rostrum  evidently  longer  than  broad,  narrowing  for  a 
very  short  distance  at  the  base  from  the  eye  to  the  scrobe,  thence 
very  slightly  and  gradually  widening  to  the  apex ;  the  upper 
.surface  almost  flat,  bare  and  shallowly  and  coufluently  punctate.

Genus  XYLINOPHORUS. 

Xylinoplwrus,  Faust,  Dent.  Ent.  Zeit.  1885,  p.  177. 

Type,  Xylinoplwrus  prodromus,  Fst. 

This  genus  is  very  closely  allied  to  Leptomius,  Est.,  and  I  can 

find  only  two  characters   by  which   it   may  be  distinguished: 

(1)  the  elytra  are  not  abruptly  marginate  at  the  baset  but  slope 
gradually  forwards  to  their  luuction  with  the  mesonotum;  (2)  the 
second  ventral  segment  is  much  longer  in  the  middle  than  the 
third  and  fourth  together. 

Faust  founded  the  genus  for  those  species  referred  to  ThyJacites, 
Schh.,  in  which  the  taroal  claws  are  connate,  but  it  also  difiiers 
froui  that  geuus  in  having  the  corbels  of  the  hind  tibia?  bare  of 
scaling. 

Range.  Northern  India  and  Turkestan.

Subfamily  II.  OTIORRHYNCHIN^. 

Apart  from  the  three  genera  Episomus,  Schh.,  Ptochns,  Schh., 
and  Mi/Uocerus,  Sclih.,  this  subfamily  is  very  poorly  represented 
ill  British  India,  nearly  all  the  remaining  genera  containing  not 
more  than  one  or  two  species  each. 

The  distinction  relied  upon  by  Lacordaire  for  separating  this 
subfamily  from  his  Eremnin^,  namely,  the  absence  of  a  post- 
ocular  lobe  or  vibrissas  on  the  prothorax,  is  not  a  very  satisfactory 
one,  for  these  characters  are  occasionally  so  much  reduced  in 
members  of  the  latter  subfamil_y  as  to  make  their  position  some- 
what doubtful ;  moreover,  it  leads  in  some  cases  to  the  separation

This  section  includes  tlie  Episomides  and  Oosomtdes  of 
Lacordaire,  which  he  himself  admits  to  be  hardly  separable.  Its 
principal  stronghold  is  South  Airica,  though  the  genus  Episomus 
contains  a  considerable  number  of  Indian  species.  The  insects 
are  for  the  most  part  wingless  and  slow-moving,  living  on  herbs 
and  low  bushes.  Some  of  the  Malayan  species  of  E2}isoimfs  are 
quite  handsomely  coloured,  but  the  Indian  forms  are  mostly  sombre. 
The  larvae  are  probably  ail  root-feeders.

In  some  sections  of  this  large  genus  the  species  are  very  difficult 
to  discriminate  with  certainty,  as  is  frequently  the  case  with 
wino-less  CuRCULio>'iDiE.  In  most  cases  the  male  genitalia  appear 
to  offer  a  safe  criterion,  but  in  a  few  instances  these  organs 
present  slight  differences,  the  significance  of  which  it  has  been 
impossible  to  determine  owing  to  lack  of  material  and  inade- 
quate locality  labels.  Some  of  the  characters  used  in  the  key 
may  appear  ambiguous  for  certain  individual  specimens.  Where 
such  is  likely  to  be  the  case  I  have  not  hesitated  to  place  the  same 
species  in  both  of  the  two  opposing  categories,  which  it  is  hoped 
will  facilitate  identification. 

It  may  be  observed  that  there  is  sometimes  a  discrepancy  in 
the  statements  of  Faust  and  myself  as  to  the  relative  lengths  of 
the  two  basal  joints  of  tlie  fuiiicle.  This  is  due  to  the  fact  that 
when  the  funicle  is  lield  straight  out  in  the  same  plane  witli  the 
scape  the  base  of  the  first  joint  is  more  or  less  hidden  from  above 
hv  the  apex  of  the  scape.  The  real  lengtli  of  the  first  joint  can 
then  only  be  seen  from  beneath,  or  the  funicle  must  be  bent  down 
at  right  angles  to  the  scape.  An  examination  of  Faust's  types 
shows  tliat'in  several  instances  he  has  been  misled  in  this  way. 
Finally,  considerable  use  has  been  made  in  the  key  of  the 
characters  afforded  by  the  relative  proportions  of  the  antennal 
joints.  It  must  therefore  be  mentioned  that,  unless  otherwise 
stated,  the  descriptions  apply  only  to  perfect  specimens;  for  the 
scaling  on  these  organs  is  often  so  thick  that  when  it  is  rubbed 
off  a  very  considerable  difference  is  produced  in  the  relative  length 
and  breadth  of  the  joints.

Type  in  the  Berlin  Museum  ;  of  E.  anmdipes  at  Stockholm  ;

The  distinctions  given  by  Faust  for  his  E.  cei/lonicus  are  its 
slightly  broader  and  shorter  shape,  the  whitish  scaling  at  the  sides 
of  the  elytra  and  the  absence  of  the  indistinct  white  spots  on 
the  upperside.  These  characters,  however,  all  vary  considerably 
in  different  specimens,  without  any  correlation  one  to  another.

This  spet-ies  is  very  closely  allied  to  the  preceding  one,  which  it 
evidently  represents  on  the  mainland.  I  have  seen  only  two  males 
and  two  females,  one  of  the  former  being  a  typical  sjiecimen  of 
Faust's.  The  structural  differences  which  distinguish  it  from 
E.Jif/uratus  are  as  follows :— The  second  joint  of  the  funicle  is 
not  longer  than  the  first,  the  elytra  are  less  acuminate  at  the  apex 
and  less  rounded  at  the  base,  and  the  intervals  5,0  and  7  are 
narrowly  carinate  posteriorly.  The  colour  differs  also,  in  that  the 
lateral  green  scaling  of  the  elytra  extends  up  to  the  4th  stria,  the 
dorsal  part  of  the  prothorax  is  also  green,  and  the  sutural  area  of 
the  elytra  is  broadly  imle  fawn.  In  other  respects  the  species 
quite  agrees  with  E.fijiiratus.

This  common  and  widespread  species  varies  considerably  not 
only  in  size,  colour  and  shape,  but  also  iu  the  structure  of  the  7th 
joint  of  the  funicle.  In  the  type  form  this  joint  is  cylindrical, 
about  as  long  as  and  only  slightly  narrower  than  the  club.  In 
Faust's  variety  bohemani  it  is  more  slender,  evidently  widening 
from  base  to  apex  and  with  a  tendency  to  become  shorter  than 
the  club.  In  a  c?  and  §  from  the  Nilgiris  (Sir  G.  Uampson)  this 
joint  has  become  still  more  reduced,  being  slightly  broader  than 
long  and  much  shorter  than  the  club.  This  form  may  be  known 
as  var.  piyer,  nov.  As  these  three  forms  of  the  7th  joint  are  not 
correlated  with  any  other  constant  differences  and  are  themselves 
variable  to  some  extent,  it  seems  preferable  to  treat  them  as  mere 
varieties.  Faust  has  erroneously  stated  that  Fabricius's  type  was 
a  uniformly  whitish-grey  example  ;  it  is  really  a  dark  brown  insect, 
Itaving  the  lighter  markings  of  paler  brown.  In  the  type  of 
E.  nubecidosus  the  paler  markings  are  almost  white,  but  they  have 
practically  the  same  distribution,  and  structurally  the  two  forms 
are  inseparable. 

Mr.  H.  E.  Andrewes  notes  that  in  Belgaum  this  weevil  was 
generally  found  on  a  kind  of  bean  grown  beside  and  between 
rice-fields.

It  is  doubtful  whether  this  species  should  be  regarded  as  more 
than  a  local  race  of  nigropustulatus.  In  the  male  genitalia  which 
I  have  examined  tliose  of  sucjax  are  slightly  broader  and  a  little 
more  curved  on  the  lower  edge  than  the  single  one  of  nufropustu-

differences  would  hold  good  in  a  long  series.

with  ill-defined  paler  spots  behind  the  middle ;  the  subhumeral 
patch  always  large  and  distinct.  The  size  is  larger  and  the  width

rather  less  rounded,  this  being  especially  noticeable  in  the  c?  •

Very  closely  allied  to  E.Jlr/ulus  var.  nigrosparsus,  but  rather 
narrower  in  form  and  with  the  dorsal  curvature  distinctly  more 
fiat,  while  the  outline  of  the  posterior  declivity  is  rather  more

sternal  process  in  E.  Jignlus  is  quite  lacking.  In  profile  the  male 
organ  is  much  more  strongly  arched  dorsally  in  the  middle,  while,

The  characters  given  by  Faust  for  distinguishing  E.  scJidnhen-i 
f rom  ^.  humeralis  (he  admits  them  to  be  "extraordinarily  similar") 
are  that  the  former  has  rather  more  slender  antennae  and  legs,  a 
slightly  shorter  rostrum,  the  elytra  less  abruptly  acuminate 
behind,  their  greatest  depth  being  behind  instead  of  at  the 
middle,  and  the  punctures  in  the  dorsal  striae  somewhat  closer 
togetlier.  After  a  careful  comparison  of  the  types  it  appears  to 
me  that  such  of  these  distinctions  as  are  appreciable  are  merely 
individual  rather  than  specific  characters. 

In  the  case  of  E.  anriviUkisi,  the  distinctions  upon  which  Faust 
lays  most  stress  are  the  greater  convexity  of  the  eyes,  and  the 
fact  that  the  flat  dorsal  outline  of  the  elytra  is  quite  continuous 
Avith  that  of  the  thorax.  The  eye  character  is  certainly  quite 
unreliable,  but  the  fiat  profile  of  typical  E.  avriviUinsi  undoubtedly 
gives  it  a  distinctive  appearance  as  compared  with  E.  Jiumeralis. 
However,  in  a  series  of  six  males  before  me  I  find  intermediate 
forms,  while  the  genitalia  yield  no  indications  of  a  specific 
difference.

Apparently  the  mandibular  a])pendages  are  usu.illy  persistent  in 
this  genus,  though  the  material  examined  is  too  small  to  enable 
this  to  be  stated  with  certainty.

Group  III.  OTIOEEHYNCHIDES. 

This  group  contains  only  a  few  genera,  but  they  are  distributed 
over  the  greater  part  of  the  world.  The  species  are  all  wingless 
and  mostly  dull-coloured,  of  medium  or  small  size.  The  genus 
Otiorrhynchus  enters  only  the  Palaearctic  fringe  of  India  ;  over  the 
rest  of  India  its  place  is  taken  hy  Pi ochus,  the  species  of  which 
will  probably  prove  to  be  very  numerous.

Colour  piceous  brown,  rather  thinly  clothed  with  minute  yel- 
lowish-grey scales,  having  sometimes  a  slightly  brassy  refiexion. 

Head  with  a  broad  and  deep  central  furrow,  the  forehead  not 
broader  than  the  eye,  the  latter  dorsal,  broadly  ovate  and  only 
slightly  convex.  Rostrum  broader  than  long,  evidently  narrowed 
from  the  base  to  the  middle,  slightly  and  roundly  dilated  at  the 
apex,  the  upper  surface  with  a  well-defined  carina  running  to  the 
inner  edge  of  each  eye,  the  space  between  these  broadly  impressed 
iind  containing  a  faint  carina;  in  front  of  the  eye  a  large  fiattened 
depression.  Antemue  with  the  two  basal  joints  of  the  funicle

I  am  quite  unable  to  agree  with  Faust  in  regarding  this  species 
as  a  Cifphicerus,  because,  in  the  first  place,  the  prothorax  has 
neither  ocular  lobes  nor  vibrissas,  and  secondly,  the  wings  are 
entirely  absent  and  the  elytra  have  not  a  true  shoulder.

The  late  Dr.  Ganglbauer  was  unable  to  trace  the  type  of  this 
species  in  the  Vienna  Museum  collection.  The  description  does 
not  agree  with  any  of  the  forms  known  to  me,  but  the  species 
seems  to  be  allied  to  P.  ajfflictus,  Fst.

It  is  impossible  to  identify  the  species  from  this  description, 
and  all  that  can  be  said  is  that  it  is  highly  improbable  that  it  will 
prove  to  be  really  a  Peritelus ;  it  is  more  likely  to  be  a  Ptochus. 

Group  IV.  TRACHYPHLCEIDES. 

This  vvidelv  distributed  group  contains  but  few  genera  and 
species,  but  this  is  probably  due  to  the  fact  that  they  have  been 
neglected  by  collectors.  The  species  are  purely  terrestrial  in 
their  habits,  and  are  all  of  small  size  and  obscurely  coloured,  being 
frequently  covered  with  an  earthy  incrustation.

with  Trachyplilceosoma  (Tr.  Ent.  vSoc.  London,  1896,  p.  92),  and  it 
even  appears  to  me  doubtful  whether  the  Japanese  form  is  speci- 
fically different  from  that  found  in  St.  Helena.  The  Indian  species 
is,  however,  quite  distinct.  It  is  probable  that  the  genus  will  be 
found  to  occur  in  Africa  also.

Group  \^  PHYLLOBIIDES. 

The  members  of  this  grouj)  are  all  comparatively  small  insects 
which,  in  the  adult  stage,  feed  on  the  leaves  of  trees  or  shrubs,  a 
fair  proportion  of  them  being  ornamented  with  more  or  less 
metallic  green  scaling.  In  the  few  species  of  which  the  early 
stages  are  known  the  larvae  are  subterranean  in  their  habits. 

The  group  is  well  represented  in  India  both  as  regards  genera 
and  species,  this  being  apparently  the  head-quarters  of  the  genus 
Mgllocerus,  the  southern  representative  of  PlujUohiiis.

the  classification  here  adopted  it  cannot  be  retained  in  this  group 
on  account  of  the  very  different  structure  of  the  mouth-parts, 
for  the  submentum  lias  a  distinct  peduncle  and  the  maxillae  and 
their  palpi  are  fully  exposed,  while  the  inaiidibles  show  no  trace

Rostrum  continuous  with  the  head  and  about  equal  to  it  in  length, 
the  base  much  broader  than  the  forehead,  the  apical  emargination 
rather  shallow  and  obtusely  angulate  ;  otherwise  as  in  Myllocerus,

Type,  Emperorrhinus  defoliator,  Mshl. 

Rostrum  stout,  longer  than  the  head  and  continuous  with  it ; 
the  mandibles  very  unequal,  the  left  being  much  the  larger  and 
projecting  (when  closed)  considerably  beyond  the  gena3 ;  in 
conformity  with  this,  the  left  geua  is  also  more  developed  and 
projects  further  beyond  the  scrobe  than  does  the  right  one,  the 
rounded  apical  excision  of  the  rostrum  being  therefore  asymmetrical ; 
the  scrobes  dorsal  and  apical,  short  and  curving  abruptly  inwards, 
so  that  the  space  between  them  is  scarcely  half  the  width  of  the 
forehead  ;  the  process  covering  the  condyle  of  the  antenna 
convex,  testaceous  and  shiny,  superficially  appearing  as  though  it 
might  be  the  condyle  itself;  mentum  small,  subcircular  and 
beai'ing  a  trausverse  row  of  four  bristles.  Antenna;  long  and 
slender,  the  scape  curved  and  reaching  the  middle  of  the  pro- 
thorax,  the  two  basal  joints  of  the  funicle  elongate,  the  remainder 
longer  than  hroad.  Protliorax  truncate  at  the  base,  the  anterior 
margin  laterally  sloping  backwards  from  above  downwards ;  the 
anterior  coxae  quite  close  to  the  front  of  the  prosternum.  Elytra 
much  broader  than  the  prothorax  and  with  prominent  shoulders. 
Abdomen  with  the  intercoxal  process  ogival,  segment  2  slightly 
longer  than  3  and  4  and  separated  from  1  by  a  deeply  sinuate 
incision.  Legs  slender,  all  the  femora  witli  a  single  small  tooth, 
the  corbels  of  the  postei-ior  tibiae  open,  the  tarsal  claws  free. 

lianr/e.  Northern  India. 

This  genus  is  nearly  related  to  Mt/llocerns,  with  which  it  agrees 
in  most  characters,  but  it  should  readilj^  be  distinguished  by  the 
remarkable  asymmetry  of  the  rostrum,  a  character  which  I  have 
never  previously  observed  in  any  adelognathous  Curculionid. 
Other  points  which  distinguish  the  genus  from  Mylhcerus  are, 
the  projection  of  the  closed  mandibles  well  beyond  the  apices  of 
the  gense  and  the  proximity  of  the  front  coxae  to  the  anterior 
margin  of  the  prosternum.

Black,  densely  clothed  with  mingled  black  and  bright  metallic 
green  scaling ;  bead  and  rostrum  green;  ])rothorax  green,  with  a 
broad  central  black  stripe ;  elytra  variable,  but  with  the  green 
and  black  scaling  fairly  equally  distributed  in  alternating  small 
subquadrate  patches  on  the  dorsal  intervals  ;  there  is  often  a 
somewhat  large  black  patch  near  the  base  on  intervals  3  to  6,  and 
occasionally  the  black  scales  greatly  predominate. 

Head  finely  striolate  longitudinally,  the  forehead  twice  as

area  almost  plane,  finely  striolate  beneath  the  scaling,  and 
with  a  fine  central  carina  in  the  anterior  part.  Antennc  reddish 
brown;  the  funicle  with  the  two  basal  joints  subequal,  or  the 
first  verv  slightly  longer,  the  remaining  five  subequal  and  mucli 
longer  than  broad.  Prothorax  transverse,  truncate  at  base  and 
apex,  which  are  of  equal  width,  the  sides  rounded  only  in  the 
middle,  markedly  constricted  in  front  and  behind ;  the  dorsum 
rather  uneven,  without  any  central  furrow  or  carina,  the  some- 
what rugose  punctures  normally  hidden  by  the  scaling,  the  set;e 
suberect  and  all  directed  forwards.  Eli/tra  much  broader  than 
the  prothorax  at  the  shoulders,  which  are  rounded  rectangular, 
parallel-sided  in  the  male  and  slightly  dilated  behind  the  middle 
in  the  female,  the  apices  jointly  rounded,  and  the  dorsal  outline 
only  slightly  convex  ;  the  shallow  striae  not  hidden  by  the  scaling 
and  containing  shallow  punctures,  the  intervals  almost  plane, 
shining  and  impunctate ;  the  scales  small,  convex  and  subcircular, 
the  green  ones  for  the  most  part  contiguous,  the  black  more 
sparse,  so  that  the  shining  surface  is  pai'tly  visible  ;  the  setaj 
slender,  long,  dark  and  erect.  Legs  red-brown,  the  femora 
darker,  with  recumbent  pale  setae  and  scattered  green  scales.

Mr.  C.  F.  C.  Beesou,  Imperial  Forest  Zoologist,  Dehra  Dun, 
records  this  species  as  defoliating  various  kinds  of  fruit  trees, 
such  as  pears,  peaches,  cherries,  etc.  Mr.  T.  Bainbrigge  Fletcher 
states  that  the  correspondent  from  whom  he  received  his 
specimens  informed  him  that  the  weevils  first  appeared  on  an 
alder  tree  (Alnus  nitida)  in  a  field  adjoining  his  orchard.  After 
completely  defoliating  the  alder,  they  attacked  his  peach  trees, 
and  then  turned  their  attention  to  the  apricots  and  pears,  apples 
being  the  last  trees  to  be  touched.  The  whole  orchai'd  was 
defoliated.

This  large  and  somewiiat  heterogeneous  genus  will  certainly 
require  subdivision,  but  this  cannot  be  accomplished  satisfactorily 
without  a  thorough  study  of  the  many  species  described  from 
other  parts  of  tlie  world,  and  tliis  I  have  not  yet  been  able  to 
undertake.  It  seems  probable  that  the  number  of  setae  on  the 
mentum  will  prove  a  valuable  character.  All  the  species  that  I 
have  been  able  to  re-examine  recently  have  only  two,  except 
M.  fabricii,  Guer.,  M.  spectator,  sp.  n.,  and  M.  suavis,  Est.,  which 
have  four ;  and  M.  tenuiclavis,  sp.  n.,  which  has  eight  or  ten. 

The  following  Indian  species  have  been  erroneously  attributed 
to  the  genus  Mijllocerus  : — 

M.  convexifrons,  Est.,  is  a  Corigetus* 
M.  saturatevirens,  Boh.,  is  a  Corigetus. 
31.  brevicollis,  Boh.,  is  a  Corigetus. 
M.  multicostatus,  Chev.,  is  a  Corigetus. 
M.  jJosticus,  Walk.,  is  an  Anibli/rrhinus. 
M.  retrahens,  Walk.,  is  an  Amhlyrrhinus. 
M.  acacice,  Stebbing,  is  a  Platytraclielus. 
M.  hirsutus,  Desbr.,  is  a  Cyphiceriis. 
M.  brachyderoides,  Desbr.,  is  a  Ftochus. 

*  The  uames  Corigetus,  Desbi-.,  Cyjykicerun,  Scbli.,  and  Plutytrachehis,  Schh., 
are  here  vised  in  the  sense  attinbuted  to  tliem  by  Faust,  but  it  is  doubtlul 
whether  after  revision  they  will  be  retained  for  these  particular  species.

Faust  niisideiitified  M.  delicatulHS,  Boh.,  as  being  the  Curcidio 
viridaaus  of  i'abricius,  aud  consequent!}^  redescribed  the  latter 
species  under  the  name  of  M.  angustifrons. 

When  I  examined  the  type  of  M.  frinr/iUa,  Fst.  (from  Malacca) 
some  years  ago,  I  formed  the  opinion  that  it  was  probabl_y  a 
synonym  of  lU.  viridanus  ;  but  I  cannot  now  state  this  with  cer- 
tainty. Dr.  Heller  has  referred  to  M.  frhujilla  various  specimens 
taken  bv  Dr.  Walther  Horn  in  Ceylon  which  I  have  not  seen 
(Deut.  Ent.  Zeit.  1901,  p.  338).  Faust  states  that  M.  viridanus 
{angustifrons)  has  only  one  femoral  tootb,  whereas  M.  fringillahas 
two,  the  rosti'um  also  being  longer  and  the  elytra  being  produced 
downwards  at  the  apex.  He  was  certainly  mistaken  as  to  the 
femoral  teeth  in  M.  viridanus,  and  the  other  distinctions  given  are 
of  dubious  value.

Black  or  piceous,  with  close  uniform  pale  green  scaling  above 
and  below,  sometimes  varying  to  grey  on  the  disk  of  the  elytra. 

Structurally  this  species  is  closely  allied  to  J/,  viridaaus,  from 
which  it  differs  in  the  following  characters  : — 

Head  with  the  eyes  distinctly  larger  and  much  flatter,  the  fore- 
head not  impressed,  much  narrower,  being  (at  its  narrowest)  only 
about  half  the  width  of  the  eye.  Hostrum  only  slightly  longer 
than  the  head  and  evidently  broader  than  long,  tlie  space  between

Colour  black,  with  markings  of  metallic  green  scaling;  the  head 
green,  with  a  quadrate  black  patch  on  the  vertex ;  the  prothorax 
with  three  black  stripes,  the  centre  one  being  broader  than  the

Type  in  the  Stockholm  Museum  ;  of  M.  frontalis  in  the  Dresden

After  examining  a  fair  series  of  both  forms  I  am  unable  to 
distinguish  31.  frontalis,  Fst.,  from  Bohemau's  species  except  by 
the  coloration  of  the  elytra,  which,  however,  appears  to  be  very 
constant.  All  the  specimens  from  Kanara  and  all  those  collected 
by  Mr.  Andrewes  on  the  Coonoor  side  of  the  Nilgu-is  belong  to 
the  var.  frontalis  ;  while  those  from  the  remaining  localities  are  of 
the  typical  form.  Another  colour  variation  also  occurs  in  the 
]N'ilgiris. 

M.  lineatocollis  var.  divisus,  nov. 

Differs  from  the  typical  form  in  having  the  upper  surface  of 
the  rostrum,  head,  protliorax,  and  the  entire  disk  of  the  elytra  as 
far  as  the  fiftli  stria  covered  with  uniform  greyish-brown  scaling, 
with  the  exception  of  a  narrow  line  of  green  scales  along  the  inner

Among  some  examples  in  the  Brussels  Museum  labelled  "  Ind. 
Bor.  (Bacon)"  there  is  one  in  which  the  central  dark  stripe  on 
the  prothorax  is  broadly  interrupted  by  green  scaling,  and  another 
in  which  this  stripe  is  entirely  a,bsent.  J\I.  tesserida,  Fst.,  was 
described  from  two  specimens  of  which  I  have  seen  one  ni 
Mr.  Andrewes'  collection.  It  agrees  entirely  with  M.  dorsatns 
except  in  colour,  the  ground-colour  being  red-bi-own  and  the 
green  scaling  replaced  by  pinkish  grey  ;  the  example  is  perhaps 
immature.

Very  closely  allied  to  M.  dorsatus,  P.,  and  differing  only  iu  the 
following  characters  : — The  scape  rather  more  slender  and  more 
abruptly  clavate,  the  second  joint  of  the  funicle  a  little  longer  in 
proportion  to  the  first,  the  third  longer  than  the  fourth  ;  the

This  variety  is  distinguished  by  its  more  strongly  rounded  pro- 
thorax  and  the  slightly  greater  dilatation  of  the  rostrum  ;  the 
paler  scaling  is  never  conspicuous  as  in  mutabilis. 

All  the  Ceylon  examples  1  have  seen  belong  to  this  form  ;  but 
it  occurt;  also  on  the  mainland,  where  it  merges  so  gradually  into 
the  typical  form  that  I  cannot  regard  it  as  specifically  distinct.

particulars  : — 

Rostrum  very  slightly  widened  at  the  apex.  ProiJiora.v  less 
transverse,  almost  as  long  as  broad,  owing  to  the  greater  pro- 
duction ot  the  median  basal  lobe,  which  makes  the  base  much  nioz'e 
deeply  bisinuate.  Elytra  with  the  striae  broader  and  the  puncta- 
tion  coarser,  the  setae  a  good  deal  longer  and  more  conspicuous  on 
the  disk.

Further  south  the  species  is  represented  bv  the  followino- 
varietal  rorm : — 

M.  discolor  var.  variegatus.  Boh. 

Tliis  differs  from  the  typical  form  in  the  absence  of  the  two 
short  basal  grey  stripes  on  the  protliorax  ;  the  under-parts  are 
nearly  always  paler,  being  sometimes  almost  white  ;  the  grey 
markings  on  the  elytra  are  also  paler  and  usually  consist  of  large 
irregular  blotches  mingled  with  small  spots. 

Boheman's  statement,  that  the  second  joint  of  the  funicle  is 
half  as  long  again  as  the  iirst,  is  clearly  an  error,  due  to  the  fact 
that  in  some  positions  the  base  of  the  first  joint  is  partly  hidden 
by  the  apex  of  the  scape.

clisappeared  and  the  colour  is  an  almost  uniform  dull  greyish- 
brown,  so  that  it  much  resembles  darker  specimens  of  M.  dentifer^ 
F.  On  the  head  and  prothorax  there  still  remain  traces  of  tlie 
typical  fawn-colour,  but  the  pale  central  stripe  on  the  latter  part 
is  reduced  to  a  mere  trace. 

Mr.  E.  P.  Stebbing  states  that  this  form  causes  serious  damage 
to  leaves  on  the  tree  Dalbtr(jia  sissoo.

M.  discolor  var.  canescens,  nov. 

This  Ceylonese  form  is  characterised  by  the  great  development 
of  greyish-\^•hite  scaling,  so  that  the  elytra  are  entirely  of  this 
colour,  except  for  a  faint  narrow  stripe  of  pale  fawn  running 
from  the  shoulder  to  near  the  apex ;  the  liead  and  a  broad  stripe 
on  each  side  of  the  prothoi'ax  are  also  fawn-colour.

The  larva  of  the  typical  form  of  M.  discolor  is  stated  by  Mr.

pest  in  some  districts  ;  while  the  beetle  itself  has  been  observed 
to  feed  on  the  young  leaves  of  the  mango,  on  loquat,  guava,  teak,

331.  Myllocerus  undatus,  sp.  nov. 

Colour  black,  with  white  or  pale  grey  scaling  ;  the  prothorax 
with  three  darker  subdenuded  stripes,  the  outer  ones  being  inter- 
rupted ;  the  elytra  with  more  or  less  distinct  large  dark  bro\\  n 
blotches,  which  generally  form  three  irregular  oblique  bands. 

Very  closely  allied  to  M.  11 -pustulatus,  Fst.,  and  only  to  be 
distinguished  with  certainty  from  some  variations  of  that  species 
by  its  narrow  forehead,  which  is  not  broader  than  the  length  of

Colour  (type  form)  black,  with  pale  grey  scaling,  the  head 
sometimes  tiDged  with  fulvous ;  each  elytron  with  the  following 
rounded  black  spots  :  one  on  the  shoulder,  one  each  on  intervals 
4  and  9  just  before  the  middle,  one  on  8  just  behind  the  middle, 
one  still  further  back  on  interval  3,  and  one  at  the  apex  of  5  ; 
these  spots  very  variable  in  size  and  one  or  more  frequently  absent. 

So  far  as  structural  characters  are  concerned  the  description  of 
M.  dentifer,  F.,  applies  entirely  to  this  species,  except  that  the 
rostrum  is  in  this  case  parallel-sided,  or  even  a  little  dilated  at 
the  apex  ;  the  antennae  are  more  slender,  the  second  joint  of  the 
funicle  being  evidently  louger  than  the  first ;  aud  the  elytra  are 
proportionately  more  elongate.

colour  being  uniform  pale  grey.

M.  ll-pustulatus  var.  maculosus,  Desbr. 

The  typical  specimens  are  of  a  pale  green  colour,  v.dth  irregular 
and  very  variable  dark  brown  patches  on  the  elytra.  The  green 
ground-colour  appears  to  be  specially  characteristic  of  the  more 
northern  examples,  those  from  Bengal  and  the  south  being  grey. 

In  spite  of  the  marked  difference  in  colouring,  I  have  faded  to 
find  any  reliable  structural  characters  by  which  this  form  can  be 
separated  from  31.  ll-imstidatus,  Fst.  Moreover,  in  the  very  long 
series  of  the  latter  which  I  have  seen  in  the  collections  of 
M.  Bovie  and  the  Brussels  Museum  from  Chota  ]N'agpur,  there 
are  a  iew  specimens  which  show  a  slight  intermediate  tendency

sort  of  broken  stripe  along  each  side  of  the  suture,  and  do  not 
extend  laterally  to  the  nuirgins  as  in  mai-moratns ;  the  prothorax

Head  exserted,  the  eyes  lateral.  Rostnim  continuous  with  the 
head;  the  scrobes  dorsal,  foveiform  and  close  to  the  apex:  mandibles 
and  mentum  as  in  MyUocerus.  Antenna'  with  the  scape  strongly 
curved  and  gradually  clavate  ;  the  funicle  with  joint  1  evidently 
longer  than  2,  2  longer  than  3,  3-7  subequal,  club  narrowly  ovate 
and  acunnnate.  liostrum  truncate  at  base  and  apex,  the  apical 
margin  oblique  at  the  sides,  the  gular  margin  not  sinuate.  Elytra 
subtruncate  at  the  base,  the  shoulders  prominent  and  roundly 
rectangular,  the  sides  parallel,  or  slightly  dilated  behind  the 
middle  in  the  5  ,  with  10  fine  punctate  stride,  the  intervals  plane

femora  unarmed,  otherwise  as  in  Mylloeeras. 

Range.  India  and  Japan. 

These  insects  can  be  distinguished  only  by  their  unarmed 
femora  from  those  small  species  of  lUyUocerus  \\-hich  have  the  base 
of  the  prothorax  truncate  and  the  tirst  joint  of  the  funicle  longer

Type  in  the  Stockholm  Museum;  that  of  A.  hrunneiis  Vit  Dresden. 
The  only  character  which  Faust  mentions  as  differentiating 
his  A.  hrunneus  from  A.  languidus,  Gryl.,  is  the  greater  length  of  the 
hairs  on  the  posterior  two-thirds  of  the  elytra.  This  feature  is 
fairly  well  marked  in  the  type  in  Faust's  collection,  and  also  in 
another  of  Stoliczka's  specimens  in  the  British  Museum.  But  a 
co-type  in  the  Indian  Museum  (also  taken  by  Stoliczka)  is  inter- 
mediate between  these  and  lawjuidvs ;  while  Bengal  examples  af

of  these  hairs  as  to  render  it  improbable  that  this  character  has 
a  spiicitic  value.

striae  shallow,  with  rather  remote  punctures  which  are  scarcely 
perceptible  through  the  scaling,  the  intervals  slightly  convex,  with 
rows  of  cm-ved  and  very  broadly  spatulate  setae.  Legs  testaceous 
brown,  with  dense  grey  scaling  and  broad  raised  setae,  the  middle

Assam  :  Mazbat,  Mangaldai  dist.  (S.  W.  Kemp — Ind.  Mus.). 

Type  in  the  Indian  Museum. 

In  general  facies  this  species  is  not  unlike  MyUocerus  hlandus, 
Fst.,  but  apart  from  the  non-emarginate  rostrum  and  the  four 
setae  on  the  mentum,  it  may  be  at  once  distinguished  by  its  much 
longer  rostrum  and  narrower  prothorax.
